I remember what made me quit facebook, way before it became Meta: the TV serie Person of interest. It gave me a big awarness of the scale of mass surveillance. I already had the project to quit because of Zuck’s shenanigans and the lack of interest i had in the platform, but this was the last straw for me.
I deleted messenger once I finally convinced the people I give a shit about to switch over to safer platforms. Hadn’t posted on or touched FB in years at that point though. That also prompted me to move to Lemmy (my only real feed-based media consumption); that plus the constant influx of doomscrolling bullshit after the latest US election.
I don’t “use” Xitter and haven’t for many, many years aside from news for legitimate emergencies that had no other alternative. Stopped using IG after they tried to copy TikTok.
TL;DR: Enshitification + increasing threat to human rights
