It's a combo of AI making it easy to flood the feed with engagement-bait (that you aren't interesting in engaging in) and users who post stuff you would engage with leaving the service or simply not posting that stuff anymore.
What's frustrating about Meta, and probably other companies that run social media sites, I'm sure, is that no matter how many times I swipe away posts I don't like on Threads, which is marked as a signal to show me fewer posts like this, I still get served similar posts or posts from the same account. Blocking takes too many pokes, but sometimes you gotta do what you gotta do. :)
