On Sunday, Twitter said it would now be banning accounts created solely to promote other social platforms, as well as any content on their platform which includes any links or user names from other platforms.

In a tweet Twitter support said it will allow cross-content posting, however the move will be sure to affect content from other platforms like Meta Platforms’ Facebook and Instagram, as well as Mastodon, Truth Social, Tribel, Nostr and Post.

Notably, absent from the list was Chinese social media platform TikTok, owned by China’s ByteDance Ltd. Musk is heavily dependent on Chinese industry for supply and manufacturing of parts for his electric car company Tesla, and has shown a willingness to show preference to Chinese entities, presumably as a way of smoothing over his relationship with the Chinese government to facilitate his business interests.

Former Twitter CEO Jack Dorsey replied to the Twitter support post by asking, “Why?” He has recently invested in social media platform Nostr. Dorsey said to another user of the policy, “doesn’t make sense.”

The decision is the latest change as the company revamps its operations following Musk’s takeover of it in October. Twitter disbanded the volunteer Trust and Safety Council, which it formed in 2016 to advise the site on decisions regarding censorship of content, just last week.

All of that comes on the heels of the torrent of changes Musk instituted immediately after taking the helm of the company. After firing top management, he let go roughly half the workforce. He instituted a subscription service which would grant a blue verification checkmark to regular users, then paused the service due to impersonations, before reinstituting it. He has battled Apple over the inclusion of Twitter in its app store, reinstated banned accounts, banned journalist accounts for doxing details of his plane’s location, and has endured a torrent of criticism over the presence of hate speech on the platform, and his willingness, or lack thereof to police it.

Musk has since reinstated many of the journalists’ accounts, after being criticized by government officials, advocacy groups and journalism organizations for infringing on press freedoms. He however left Keith Olbermann’s account banned. Olbermann had used the twitter account of his dog to complain about the ban on his main account.

In leaving Olbermann banned, Musk tweeted, “Olbermann tweeting from his dog’s account still makes me lmao.”
