Yeah but what they actually do is removing themself from market place. If I were looking for a startup, I would check for someone banning EU users, with prospective idea and copy what they have done, but GDPR oriented and voila, I am first on the market, slowly taking over the original site bussiness in EU and later the world. EU is a huge marketplace and you really need to be extremly short minded to avoid it due to some stupi legislation, not to mention that as a US cityzen I would abandon any site not going for GDPR compliancy as they are saying to me, between the lines, "we are bastardising my data". Like seeing a laser pointer on your forehead.
