Jack Dorsey and Elon Musk pile in on Meta's new Twitter competitor

• Twitter's cofounder Dorsey appeared to complain about the app's privacy policy.

Jack Dorsey and Elon Musk are piling in on Meta's new Twitter rival, Threads.

Posting a screenshot of Threads' privacy policy on Monday, Dorsey tweeted a jibe that appeared to reference Meta's difficult history with user privacy.

"All your Threads are belong to us," he wrote.

Within an hour, Twitter's owner, Musk, had chimed in to share his agreement in the comments. Musk has been taking other public swipes at Meta's new offering, which is set to launch on Thursday amid a fresh wave of Twitter chaos.

Dorsey appeared to take issue with the app privacy policy stating that data around health and fitness, financial information, user content, and browsing history among other things may be collected and linked to a user's identity.

Some Twitter users were quick to point out that the privacy policy shared some similarities with Twitter's. However, Twitter's privacy policy did not appear to reference health and fitness or financial info.

Meta, Facebook's parent company, has suffered a series of privacy scandals in recent years that have resulted in large fines and high-profile investigations. In May, Meta was hit with a record-breaking $1.3 billion fine over data-privacy breaches. The company said at the time it plans to appeal the ruling.

Meta has linked its new Twitter competitor to Instagram rather than Facebook, leveraging the platform's 2 billion users, while also avoiding association with the central platform in Meta's privacy issues.

Meta did not immediately respond to Insider's request for comment, made outside normal working hours.
