Reddit was hated and still is hated because people actually challenged eachothers views (mostly) constructively while also organizing and fighting for change when possible. Upvoting, downvoting, commenting, and engaging all equally mattered. Until one day spez and all the reddit mods decided to let their platform eat shit.
There were places that circlejerked, no doubt about it, but what everyone fails to realize is that reddit was a place for pretty much everyone. So if you thought that subreddit was a circlejerk, feel free to join or make a different one. Like open source software getting forked.
All these different social medias want us to be trapped in some sort of bubble through the illusion of choice. The short character limit is also what causes these sites to always be inferior to places like reddit and lemmy whether they like it or not. No one has a chance to fully expand on what they actually think or cite sources instead of being blasted immediately after their first post by getting blocked, cancelled, or moderated to oblivion.
toothpaste, shampoo, lotion, such a mindless purchases for me but thats only because I figured out which ones I like
