Unpopular Opinion: Xitter going bad is the best thing that ever happened to the Web
Anyone sane has left Xitter already and the crazies stay on their own platform, making the Web generally much more pleasant, as less and less sites link to Xitter.
It's not dead though, it's still linked to everywhere, from big news to niche communities because it still has that critical mass and inertia.
And I have to be cynical of the Fediverse, but realistically, what replaces it, at least here in the US? Discord? No, thanks, I'd at least rather have information be public.
I'm speaking as someone who has never used Twitter, but I can't ignore it, as much as I'd like to.
If you think X is getting linked at anything approaching the level Twitter was back in the day ... where have you been? That platform is slowly bleeding out his billions of investment (well, some of his, but lots of other peoples' money I don't mind seeing burn, either)...
It's so big that it can take a lot of bleeding before it dies. It doesn't help that there is no significant enough consensus yet on an alternative.
It seems like some people are flocking to bsky, probably because it has better visibility and seems more accessible than Mastodon ("What's an instance? How do I pick?"). Others are heading to Threads just because it's there already.
If enough people move to some other platform to generate a critical mass, they'll pull others too. Until then, inertia will keep X rolling a good while to come.
I share your hope. I'm just offering the caveat that it might not go as quickly and smoothly as you expect (unless I'm reading your comments wrong - do correct me!)
