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.
Because they’d heard of them.
The power of the fediverse is nothing next to the power of the normieverse and a couple of billion dollars in advertising money.
