Is the Fediverse stalling?

I'm genuinely interested in people thoughts about the Fediverse because here in the UK it has massively stalled in 2025, like a lot of things. I am seeing way less posts from UK people and way less interaction and general use in fact. Most seem to have stopped social media use to be fair, and I know a lot of that is to do with my age (old fart here, 56 laps round sun and counting) but the numbers game look poor from my point of view. Do we think the Fediverse has a future now after useage appears to be going downwards? Is it a UK thing? (well I know the UK is weird but hey)
