Twitter has lost over 10% of its users and engagement/monthly active users is down, Musk even admits they’ve lost users. Traffic is also going down with the API change/requirement to be on Twitter proper, as well as limiting the number of tweets one can see.
Considering how much a Twitter is bots, that means the number of actual people who left is actually much higher. So yeah, something did change lol just because you haven’t noticed it doesn’t mean it isn’t happening.
Edit: I’m not sure why you are talking about left and right users tbh. Seems like you’re kind of shoehorning a “both sides“ comment since no one is talking politics here.
