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.
Initially I heard about mastodon as a Reddit alternative, it was not. I have never been a Twitter user. I did create a Twitter account at some point, I only ever used it to post images from when I was at occupy Wall Street, and then later to follow a couple accounts for updates (Sean Murray of Hello Games). When I opened my own business I created a Twitter account for that specifically and used it to send out coupon codes and stuff like that.
Once musk bought Twitter I deleted both of my accounts. I had totally forgotten about mastodon, so I got on the list for a Bluesky code. Around the time I got my Bluesky code I heard about Lemmy, and then heard about mastodon again. Had my Bluesky code not arrived when it did, I would have created a mastodon account for my business instead of Bluesky. Since I never use either it is a moot point for me.
