If you think the only reason to use a self-hosted social network is if you want to circumvent the laws, you're making the same argument as only wanting privacy if you've got something to hide. YouTube ran an algorithm to delete "extremist videos" and accidentally irreversibly deleted a bunch of historical evidence of destruction of Syrian historical sites. Shit like that happens all the time when someone else is in charge.
@Gargron was it irreversibly deleted? That aside, I still can't wrap my head around people having the only copies of their videos on youtube or their photos on google photos. Back to the analogy of 'hey neighbor, can I store my stuff in your garage for free indefinately?'
