Is so, many US registrars would be suspend wholly .Many of them hosted a large number of spammers and fake sites without giving a toss about it - as long as they got paid., even with stole credit cards. Most of them decided that it was more profitable to sell a large number of cheap domain names, without checking registration data - of course that means to close both eyes on who registered what.
ICANN acts the same way, as long as it people are paid handsomely for looking at their bellies buttons, they don't care at all about actual issues and upcoming ones - as we've see in this case.
GDPR wasn't meant against FB or Google - it was meant to protect citizens' data, regardless who collects and manages them.
