In my experience which is worth one (1) datapoint, people talk about all sorts of stuff.
Yes, people do talk about the fediverse as part of it, but usually it's about how we can make it better rather than how our corporate overlords have made it worse.
And I'd say that fediverse metacontent is less than 1% of my feed, so it's not universal, it's very much down to how you set things up.
Places like kbin will get more because they're newer. I'm not on Threads or Blue sky or whatever but I imagine a lot of the chat there is about their own shiny new thing as well.
