As far as the GDPR goes, only webmasters choosing to ban entire countries of users out of greed (wanting to unfairly profit off users) or laziness (not caring enough about the privacy of their users) or spite (punishing users because you don't like the GDPR) can achieve the splitting you describe. If it happens, it would be their decision, and thus their fault.

Real talk though, again: you say you personally feel the GDPR is vague. If you have questions about the GDPR, ask them, and I'm sure smart folks at HN will be able to help you find answers and overcome obstacles. You can build and not break laws, whether GDPR or ITAR, we can help. If you have troubles building, share them with us, let us advise you. Nobody's saying it'll be zero work, but nobody's entitled to run a business doing whatever it wants with zero work, either, and shouldn't expect to.
