Earlier quoted context omitted.
Because bitter HN users will call you shady if you don’t fully comply with their pet law, no matter how ambiguous or onerous :)
This "pet law" is the law of 500 million people, has been in effect for two years (two years was a grace period to comply with it), and exists exactly because shady businesses didn't even comply with existing data protection laws. It's not "bitter HN users". It's bitter European citizens. No wonder that it's mostly American companies who have the most trouble complying with it.
Having grown up in Europe I'm much more sensitive to privacy concerns than most Americans, but it's not proper to assume that anyone who just blocks European visitors is up to something nefarious. It just doesn't make business sense for everyone to comply.
