Thank you. Lots of different views. Will read. There was also recently an talk on hard fork on this issue. https://m.youtube.com/watch?v=tZSteN2g5yM

My personal opinion is that things that let you curate your own content like lemmy/reddit is good(ish) and things where the company curate the feed is more a trap. But i am not a scientist, just curious.

I am not saying you are wrong. But you need to show us unbiased research that contradict the research that does show a link.
Heck even meta’s own research (as biased as it gets) show a significant link.
