I have wondered this, it's possible there are private groups/relays outside of our ability to see them. And they'd have to make themselves known/mentioned it elsewhere or something. It's somewhat unlikely, but possible.
More likely social alts aren't getting much attention atm, Bluesky is wanting a bit too.
Also I think with all this breaking news and ww3 happening every week xitter is still the place people look. I mean eve khamenei has a twitter, being on an alt is like having lag, people are waiting for reports from there. Whereas you can just be there directly. (I'm not saying this is a good thing, just saying that's how it is/seems).
