I don't get the complaints about how hard GDPR is and having to understand it all. If you're based in the US, have you read the actual DMCA document? CFAA? California S.B. 1386? TWEA? ADA? Or at least any interpretations of them and validated that you comply?
If not, then worrying about GDPR which is mostly not enforceable in the US sounds disingenuous.
Not saying anyone thinks it's a good idea. I'm saying I haven't seen that many comments, annoyed people, and general discussion about other laws, which actually impact US people and can be enforced there.
I'm guessing they also ignore those laws, because of posts like this one. If you're running a business complying with regulations, you likely already know how to block a country. I mean, you keep track of the current embargoes and block relevant countries, right?
