Twitter's Battle with Substack: Restrictions and Disabling Features.

Substack founders have criticized Twitter's new restrictions on promoting tweets with links from the publishing platform, stating that writers' livelihoods should not be tied to platforms where they don't own their relationship with their audience and where the rules can change on a whim. Twitter users noticed that they couldn't like, reply to, or retweet some tweets that had Substack links in them, and Twitter hasn't explained why it made the change. The Substack founders say this serves as a reminder of why writers need a platform that rewards great work with money and protects free speech.
