So imho this can not happen soon enough, people think the EU is actually protecting them when it isn't. I hope more countries join as well
I doubt a majority of Facebook users would agree with it being prevented from operating in European Union due to their servers being in the US. This is a precedent that can and will lead to undue internet restrictions in the future. So while I share your concern that we should do more regarding data protection, I'm not sure this is the way to go.
The far majority of my social circle doesn't use Facebook and removed their accounts with all the bells and whistles years ago
Imo DNS banning software that is breaking privacy laws is not to much to ask to. Anyone can use a different DNS, nobody cares.
I am usually against banning, but we ban other dangerous scam things too in order to protect customers because sorrily this is the best we have.
