Instagram actively hides pics from my step kids, nephew and niece to show me "reels" from people I don't follow. Last night a photo from my step daughter flickered briefly and then was lost. I couldn't find it again until this morning. I literally can't find their content anymore without scrolling and dodging videos that keep popping up.
Youtube broke entirely a few months ago. The content creators I've subscribed to are now rarely in my feed which is full of "recommended for you" videos and movies for rent. Several content creators I follow have their business dying from sudden drop in ad revenue due to the changes.
Facebook does this weird thing were after someone I know recommends a video, my feed switches to recommended videos entirely until I click back to home. Stuff appears from friends or family days after posting, now at the top of my feed.
Twitter is, surprisingly, the least broken, at least I mostly still see the people I follow. I still miss stuff because of the algorithm, but it's not, yet, forcing a ton of stuff I'm not actually following down my throat. And the ads are still clearly ads.
