The 17 biggest tech scandals of 2017

In February, a former Uber employee named Susan Fowler said in a personal blog post that she was sexually harassed and experienced gender bias during her year at the company.

The allegations were made in a post Fowler titled "Reflecting On One Very, Very Strange Year At Uber," which detailed how she was propositioned for sex by her manager, was ignored and lied to by HR, and was excluded based on her gender.

CEO Travis Kalanick immediately launched an internal investigation into sexual harassment and gender discrimination at Uber, which eventually led to his own resignation.

Meanwhile, Fowler has a movie deal, and is expected to have a book deal soon.

In February, Disney dropped YouTube star PewDiePie after he posted a series of videos that featured anti-Semitic messages.

PewDiePie, whose real name is Felix Kjellberg, is known for making gaming videos that often contain expletives and other colorful language. While a review by the Wall Street Journal found several videos containing anti-Semitic jokes, it was a video from January 11 that likely cost Kjellberg his deal with Disney. In the video, Kjellberg hired two men to make a sign that read "Death to All Jews" using the freelancer website Fiverr, where you can pay someone $5 to do something for you. Kjellberg later said the video was a joke that had gone too far.

Soon after, YouTube killed the second season of "Scare PewDiePie," and removed Kjellberg from its preferred advertising program.

Then, in September, Kjellberg used a racial epithet in an expletive-laden outburst during one of his popular live streams. He later apologized, saying, "I'm really sorry if I offended, hurt, or disappointed anyone with all of this."

In an explosive lawsuit filed in February, Waymo accused Uber of using stolen technology to advance its own autonomous-car development.

The suit, filed in the US District Court in San Francisco, claimed that a team of ex-Google engineers led by Anthony Levandowski stole the company's design for the LIDAR laser sensor that allows self-driving cars to map the environment around them. Uber denied the claims.

Months later, the lawsuit has gotten ugly. In October, Waymo sought at least $1 billion in damages and a public apology from Uber as conditions for settling the suit, but Uber refused.

And in December, an explosive letter was unsealed that contained allegations that Uber had internal teams tasked with bugging hotels, infiltrating sensitive WhatsApp groups, and obtaining trade secrets from its competitors.

In late March, advertisers pulled their ads from YouTube after The Times' investigation revealed that their ads appeared alongside extremist or hate content on YouTube.

More than 250 brands reportedly froze all their campaigns with Google aside from search, after the issue — which first seemed isolated to the UK — spread globally. Major US advertisers soon began to boycott the online ad giant too, and according to The Times, the money pulled amounted to hundreds of millions of dollars.

At the time, analysts predicted that Google could lose up to $750 million from the boycott. By June, the Wall Street Journal reported that while some big brands has returned to advertising on YouTube, many had not.

June: Six women working in the tech industry told The Information that Binary Capital cofounder Justin Caldbeck had made inappropriate advances to them while in a business setting. In the same month, "Shark Tank" judge and investor Chris Sacca issued an apology for helping make tech hostile to women after being accused of touching a female investor without her permission at a tech event in 2009.

July: Dave McClure, the founder of startup incubator 500 Startups, resigned from his position as general partner following an investigation into claims of sexual harassment. In that same month, a former BetterWorks employee sued the company and its CEO Kris Duggan over allegations of assault, sexual harassment and a hostile work environment.

September: SoFi cofounder Mike Cagney resigned as chairman and announced he would step down as CEO by the end of the year amid allegations of widespread sexual harassment at the company.

October: Tech blogger Robert Scoble was accused of sexually assaulting two women and behaving inappropriately with other women in the tech community.

December: Venture capitalist and early Uber investor Shervin Pishevar resigned from VC fund Sherpa Capital after multiple women accused him of sexual misconduct. He has now been accused of sexual misconduct by six women in total.

About 20,000 Pokémon Go players traveled from all corners of the world in July to Chicago's Grant Park for the first-ever Pokémon Go Fest.

The festival promised players the chance to catch rare Pokémon throughout the day. But rampant server outages and poor cell service quickly turned the event into an experience so disappointing that the game's owner, Niantic Labs, issued refunds and $100 worth of in-game credits for each ticket holder.

In August, senior Google engineer James Damore penned an anti-diversity manifesto that spread through the tech world like wildfire.

The manifesto criticized company initiatives aimed at increasing gender and racial diversity and argued that Google should instead focus on "ideological diversity." The 10-page treatise also claims that biological difference between men and women are responsible for the underrepresentation of women in the tech industry.

Damore was fired from Google shortly thereafter, and immediately filed a complaint with federal labor officials. But Damore's firing also sparked a debate over freedom of speech, and even calls for Google CEO Sundar Pichai to resign.

In September, Facebook said it had found evidence that fake accounts "likely operated out of Russia" purchased thousands of ads during the 2016 US presidential election.

The ads covered a wide range of hot-button political issues, including the Black Lives Matter movement, LGBT rights, immigration, and gun rights. Some were designed to stir support for then-presidential-candidate Donald Trump.

Facebook said the ads were designed to deceive the public and distort political sentiment ahead of the election, and estimated that 10 million of its users saw the ads.

In October, Facebook turned over to Congress copies of 3,000 ads that it were most likely bought by people in Russia, and in November, representatives from Facebook — as well as Google and Twitter — testified before the congressional committees investigating Russia's alleged interference in the election.

In September, credit-reporting agency Equifax revealed that the personal details of up to 145.5 million US consumers were potentially accessed by hackers between mid-May and July 2017.

CEO Richard Smith announced that he would "retire" shortly thereafter, and in October, he spent hours getting battered by lawmakers in testimony about the breach.

Equifax is now the subject of hundreds of lawsuits and is still being investigated by dozens of government agencies.

While sites like Google, Twitter, and Facebook spent much of 2017 combatting the spread of fake news on their platforms, it was ineffective at the worst possible time: after the deadly mass shooting in Las Vegas in October.

Shortly after the shooting took place, viral fake-news stories showed up across the popular social media platforms, and even landed at the top of Google Search results. A 4chan message board about the shooting hit the top of Google's Top Stories, which is not vetted by humans.

The 4chan board posts were quickly picked up by far-right website The Gateway Pundit, a far-right website that has spread misinformation in the past. The story went viral.

It wasn't just Google, though: On its "safety check" page, Facebook linked to a story on a self-proclaimed alt-right blog that suggested the festival was "more like the kind of target a left-wing nutjob would choose." And on Twitter, users like the far-right provocateur Laura Loomer went viral by stoking speculation that Islamic terror groups were responsible for the shooting.

In a statement to Business Insider at the time, a Google representative said the link to 4chan was algorithmically removed within several hours of it appearing, and both Facebook and Twitter said they were reviewing and removing those types of posts.

Yahoo announced in October that it believes a staggering 3 billion user accounts were stolen in 2013 — triple the 1-billion figure it gave in December 2016.

The latest number means that every single Yahoo account was affected by the hack. The hacked user information included phone numbers, birth dates, security questions and answers, and "hashed," or scrambled, passwords, Yahoo said in a list of frequently asked questions on its website. The information did not include "passwords in clear text, payment card data, or bank account information," the company said.

In November, a popular Medium article and a New York Times story both revealed the thousands of disturbing videos on YouTube that target young viewers.

The videos frequently depict popular children's characters, but are often knockoffs made by obscure or anonymous producers instead of the studios that own the rights to the characters. The knockoff videos show those characters in lewd, violent, or disturbing scenarios, but YouTube lists them alongside the official videos from the characters' owners.

Following the revelations, YouTube said it would step up its efforts to prevent children from seeing that type of content by restricting access to inappropriate videos to users that are logged into the site and are older than 17. Any age-restricted videos are already automatically blocked from showing up in YouTube Kids, the company's app that's designed for children under 13.

Uber paid hackers $100,000 to cover up a 2016 cyberattack that exposed the personal data of 57 million people, including both riders and drivers, Bloomberg's Eric Newcomer reported in November.

The data breach, which occurred in October 2016, was not made public until November when Uber quietly published a blog post about the incident.

Among the info stolen was trove of data including the names, emails, and phone numbers for 50 million riders globally, as well as the personal information of 7 million drivers. This included US drivers license numbers, but no Social Security numbers, according to Uber.

Two of the people responsible for Uber's handling of the breach are no longer with the company as a result of the findings.

Game maker EA launched a gorgeous new "Star Wars" game in November called "Star Wars Battlefront 2." But well before the game was released, it became embroiled in controversy.

While "Battlefront 2" itself is a stunning game, that was overshadowed by the way the game implemented in-game purchases.

Players were able to buy currency within the game that could be spent on items like character enhancements. But people took issue with the fact that the game's developers tipped the scales in favor of people willing to spend more money, known among gaming fans as "pay to win."

On top of that, several major Star Wars characters — Princess Leia and Luke Skywalker included — weren't unlocked to begin with. Redditors soon discovered unlocking them would take hundreds of hours.

As controversy swelled, an EA representative issued a statement on Reddit, but it only served to make fans angrier — it quickly became one of the most downvoted Reddit comments of all time. Soon after, EA dropped the in-game costs by 75%, then on the night before the game launched, dropped in-game purchases altogether — but said they'll return at a later date.

In November, a security flaw was discovered in the latest version of MacOS, called High Sierra.

On an up-to-date Mac, users could gain access to change protected settings in certain circumstances by telling the system their username is "root" and providing a blank password.

Apple quickly released a software update to fix the bug and said in a statement, "We greatly regret this error and we apologize to all Mac users, both for releasing with this vulnerability and for the concern it has caused. Our customers deserve better."

In December, data from Geekbench showed that Apple has been slowing down the processors on iPhones with older batteries, presumably to boost performance. The data fueled long-held conspiracy theories that Apple purposely slows down older iPhones to sell new phones.

Apple ended up confirming that it began slowing down old phones last year, but says it did it for an altruistic reason: not to make older iPhones slower, but to help prevent them from suddenly turning off.

Still, Apple immediately faced class-action lawsuits filed by furious customers and caused outrage, even among Apple's most loyal fans. Apple soon issued an apology and offered low-cost battery replacements for customers with an iPhone 6 or newer.
