It's not like "they" are some unknown quantity though, it's the Facebook people. It's not weird or unreasonable for people to not want the company that got fined literally a billion euros for data privacy violations just a couple of months ago to get involved in a thing they like
I'm not on Facebook but I know people who are, and they are just ordinary people who made a poor choice and didn't read the terms and conditions. It's all those people who you are excluding, not just Facebook employees.
All of those people are welcome to make accounts elsewhere on any Fediverse instance, though, just like they were before the launch of Threads. They're not banned. They're not being punished either. There's just going to be less stuff on Threads.
They already spread medical disinfo like wildfire, got someone who sold our state secrets to the highest bidder elected, and house sociopathic terrorists like libsoftiktok. That's enough.
it's more like suspending someone who has engaged in bad behaviour in the past and is likely/promising to do it again. if you own your own fediverse site, you decide what the rules are and how to enforce them.
the difference between the fediverse and the corporate-controlled social media sites is that you can actually enforce your rules against larger companies on your own corner of the internet.
I know very little about the machinery that makes the fediverse work, so forgive me if this seems ignorant: What’s to prevent a malevolent entity from writing their own version of the fediverse that is compatible with the current version and uses the “EEE” philosophy to essentially take over, grow, and kill (or overwhelm) the ‘verse we all use now?
