Twitter is censoring Substack links by making the posts impossible to reply to, like or retweet. While quote tweeting works, simply pressing the retweet button surfaces an error message: “Some actions on this Tweet have been disabled by Twitter.”

The timing of this action doesn’t seem coincidental. Two days ago, Substack launched its Notes feature, which looks a whole lot like Twitter. Unlike other new Twitter alternatives, Substack has a huge advantage: people actually use the platform, and many writers already have massive followings there. Such writers include Matt Taibbi and Bari Weiss, who Twitter owner Elon Musk partnered with to publish “The Twitter Files.”
