I disagree. It's certainly not the case for me - Instagram has become an app I open out of habit or because I got a notification, remember that it sucks now, and close again. But more generally, this is two things: the tail wagging the dog, because Instagram pushes reels hard you get more engagement there as a creator which pushes people into them; and the fact that low quality engagement is a poor proxy for what people actually want. Instagram can show me videos of women in sheer tops all day, and if I am bored it is mindlessly engaging, but it is never what I want. What I want is to skim over 50 posts from people I care about, and maybe interact with one or two of them. I think am far from alone in what I want, but Instagram does not want what I want, because it is harder to keep me looking once I get to the end of my feed, and harder to put ads in front of me I don't scroll past almost immediately.
