This is why massive companies like Meta and Alphabet needs to be nationalised. They simply have too much power over lives of billions. This article is just another reminder of this. At scale that Meta operates, this algorithmically decided domain blockings mean nothing to them, but everything to hundred's of non-profits. There need to be legally mandated protections so things like this never happen again.
I don't think nationalisation is the answer, imagine the additional layer of bureaucracy dealing with a government entity. Large companies like Facebook need to be regulated by the government, there needs to be laws in place for stuff like this.
My guess is that American companies like to pretend it doesn’t matter in case it gave idea to US customers and silently fight it in courts in Europe.
