And I can choose the ones that moderate the way I want?
Thus my emphasis on why most people would rather just deal with centralized social media than the fediverse. That way there isn't any additional research to do, you just make an account and tolerate the terrible moderation. No additional steps about worrying about if the specific server you're on is agreeable, no need to worry about self-hosting.
Eg none of my friends were interested in doing all that research, so the only way to get them into the fediverse was on my server. Now that they're there, they're able to use it however they want and just block for themselves whatever they personally don't want to see.
Of course servers have the option to do whatever they want, which is great, but that doesn't mean they can't be criticized.
It's just that to a lot of us, that isn't a thing that makes much sense to be criticized. Like complaining that there's no lovely exhaust smell from an electric car.
To a lot of us it not being a massive central server that is instantly viable for everyone on the planet is the good thing.
Many of us don't want everyone on the Fedi. We want people interested in the premise of what the Fedi gives. Which inherently is tied to being okay with uninterested people not joining.
I've been on Mastodon for ~8 months (or w/e). Back in November, all the people claiming it was just a fad, that it would never exceed Twitter, were doom saying all through Jan/etc when the flood didn't cripple Mastodon. Yet there i and everyone i knew on it was, just using it.
The only interesting/concerning thing here is just having Facebook on ActivityPub.
