The fans of this law seem incapable of separating its intent from the practical realities of the underlying principle it introduces. Namely, that every website on the internet is now subject to any laws by any jurisdiction in the world (down to the city level) because some subject of that jurisdiction might visit their site. It’s insane.

Fast Forward 10 years: "and that's how decentralized internet was born"

Did you just compare a data privacy law with some hypothetical obscure privacy law? Amusing. Per your analogy, if German website still wants to be shown in SA then either they get SA govt on board with w/e content they are serving (bare knees in this case) or they stop traffic coming in from SA altogether or they simply comply with SA local laws and censor content (bare knees). You should do some research on how US based website show content in Chinese region.

That's China doing the blocking... You're saying I should have to perform custom work for a legal case that I'm not under jurisdiction of.

By any means I am not a fan of GDPR.
