Elon Musk’s Twitter Censored Substack, One of Its Competitors

A number of companies, including big names such as Meta, owner of Facebook, are working on competing products similar to Twitter. One of the first to go public was a service called Notes from Substack, a newsletter platform.
Shortly after Notes launched, Twitter borked Substack on its platform. The company blocked users from retweeting, liking, or commenting on Substack links, and made it so Substack users could no longer embed tweets in their newsletters. Users even reported that Twitter made it impossible to search for the word “Substack” on the platform.
Musk tweeted, without evidence, that “Substack was trying to download a massive portion of the Twitter database to bootstrap their Twitter clone, so their IP address is obviously untrusted.” Substack denied this allegation. Musk also said Substack links weren’t blocked, which was demonstrably untrue, not to mention the fact that the situation was confirmed by Gizmodo and many others. Regardless, IP addresses have nothing to do with searching for the word “Substack” on Twitter.
