What made everybody move from a corporate social media platform to another corporate social media platform instead of the fediverse?
After all, the Fediverse and Activitypub is much more mature than Bluesky and the copycat AT protocol or Threads and … whatever they use.
Threads was because if you had an Instagram account it ported over.
Bluesky was the Twitter clone made by the old Twitter CEO.
Most people didn’t have a problem with Twitter being a corporation, they had a problem with the new owner of the corporation making the experience terrible with his new changes.
