Matt Taibbi, a journalist who worked on the “Twitter Files” series of articles about old business decisions at Twitter, has said he’ll no longer use the social media platform. Taibbi is apparently frustrated by Twitter’s recent decision to heavily restrict all links and tweets about Substack following that company’s announcement it would be launching Substack Notes, a short form social network and potential competitor to Twitter.

Any Twitter user who even tries to retweet a post from Substack is met with a notification, “some actions on this Tweet have been disabled by Twitter,” a move that has angered many users, including Taibbi.

“Earlier this afternoon, I learned Substack links were being blocked on Twitter. Since being able to share my articles is a primary reason I use Twitter, I was alarmed and asked what was going on,” Taibbi wrote at his Substack on Friday afternoon.

👀 @ElonMusk (Account that mostly reposts old memes) is no longer following @mtaibbi

[Wow — that went south quickly. Apparently, the new Substack Notes feature is seen as a competing platform by Musk to Twitter. Or at least that’s the explanation, although I can’t figure out *why*. This is very short-sighted on Musk’s part, especially given Taibbi’s defense of him. — Ed]
