The three things cited in the post summary? Never been on them. I never ever heard of one of them. It seems to me that it's more that these few platforms are struggling, and other (twitter/x, reddit, facebook, and other) just keep sailing smoothly.

I don't post because I know no one will see my posts, and I don't want to give them my data without feeding my narcism in return.

Social media was fun until my family joined and scrutinized my posts, and then I lost all my friends

I have Instagram installed but frozen with "Ice Box" android app.

I open once per day or 2 days to catch up with some friends status. But I don't see those neverending reels anymore.

I deleted all my big tech accounts, and lots of people are posting on the fediverse.

Well, it sucks. A certain South African Dutch chump with a Napoleon complex is 90% of the reason why.
