By the way, We have joined hundreds of admins and mods across the fediverse in pledging to block Facebook/Meta-owned servers (and have already blocked a couple likely domains): https://fedipact.online/
Facebook's right-wing bias, lack of moderation, and extremely successful attempt to essentially replace the web in vast portions of the world have been disastrous for the Internet and society in general. I have also seen several cycles of giant corporations running services using open protocols and, once they've captured a big enough userbase, switching to a proprietary system and then killing it off whenever they feel like it.
A better Internet is possible—but not funded by ads and run for profit by a single giant evil corporation.
