Rubens,
I think I see where the disconnect might be. Section 3.2.2 says "Extraterritorial reach as described in section 3.2.1 above will apply, for instance,
when registrars and registries established outside the EU provide their domain
name registration services to natural persons in the EU."
Are you interpreting that to mean: "If a registrar/registry outside of the EU markets/offers their services to natural persons in the EU (that is, you either have some customers in the EU or you potentially could), then they are fully subject to the GDPR for all of their registrations."? Because I think that's a misreading of it. I think it means "with respect to the actual provision of services to a natural person in the EU." In other words, taking it to an extreme, I think you might be interpreting the Hamilton language in 3.2.2 to mean that all of a non-EU registrar's registrants are entitled to full GDPR protection if that registrar has even a single potential customer in the EU. However, I think they mean that even a non-EU registrar has to ensure that any natural person in the EU is afforded GDPR protections (and I'd agree with you on that -- my own company has been deep into GDPR compliance even though we aren't in the EU).
