Yeah, I am currently using a PieFed instance that is behind Cloudfare, because my regular instance has problems. But I have preferred instances not behind Cloudfare.

AWS, it’s not really legal for any public institutions in EU to use AWS. Many do anyway, though. So yeah, some stuff might break in the society. But not that many things I use personally. Hopefully they have backups of their code on their own servers as well, so that if AWS ever disappears, they can quickly run the same code on some sensible platform. Wonder where their databases are physically located, though :D

Funny, but for me very little would change. The only one of those I use even occasionally is YT, and the videos would start appearing elsewhere. Peertube, maybe?

EDIT: Oh, I’d lose my steam library. That would be a nuisance!
