Elon Musk's ex-lieutenant took a jab at the billionaire after he changed the company's sign to 'Titter:' 'Who hurt you?'

• Twitter's former head of ad sales, Robin Wheeler, took a dig at Elon Musk over his "Titter" sign.
• Wheeler was a top lieutenant under Musk when he first bought the social media company.

Twitter's former head of ad sales, Robin Wheeler, slammed Elon Musk on Twitter after the billionaire changed the company headquarter's sign to say "Titter."

"Who hurt you?" Wheeler tweeted on Monday in response to Musk's post about the sign. "To think I actually believed you would do good things for the amazing service we built. SMH."

Wheeler did not respond to a request for comment from Insider ahead of publication. Musk also did not respond to a request for comment, and Twitter responded with an automated message.

Wheeler was identified as one of Musk's top lieutenants shortly after he took over the company in October, appearing alongside the billionaire in front of over 100,000 Twitter users in an "Advertiser Town Hall" that was designed to assuage concerns about the company.

She attempted to resign from the social media company in November, but Musk convinced her to stay. He ended up firing Wheeler about a week later after she refused to lay off more of Twitter's staff, Bloomberg reported. Since taking Twitter private, Musk has eliminated over half of the company's workforce.

The former executive had worked at the company from 2012 and 2020, and had returned to the company several months before Musk went through with his $44 billion purchase, according to her LinkedIn profile.

On Sunday, Musk said on Twitter that the "W" on the Twitter sign at its San Francisco headquarters had been painted over.

"Our landlord at SF HQ says we're legally required to keep sign as Twitter & cannot remove 'w', so we painted it background color," the billionaire tweeted along with a picture of the sign.

Before Musk announced the change, several Twitter users had posted pictures of the sign in which the "w" appeared to have been taped over.

It's not the first time Musk has incorporated a joke into his work.

Last week, he replaced Twitter's homepage logo with a Shiba Inu, and Musk has said he named Teslas Model S, Model 3, Model X, and Model Y because the letters spell "S3XY."

The billionaire's propensity for dirty jokes has even been cited in some lawsuits from former workers against his electric-car company.
