I boycotted with the API nonsense a few years ago and noticed I didn't miss it that much. Haven't really been back since. When a web search leads me back, it seems to have gone downhill with lots of low effort and bot-ish posts.
It was fun while it lasted, but with everything going on it often feels nicer to just not look at the internet and do something else. Rage baiting, copy cat posts and spam have become so common on Insta even that's become harder to enjoy.
It's been wild to see the Dead Internet Theory mature in real time after reading about it like... 15 years or more ago.
