Also, your Twitter quote shows another issue: conflating GDPR with the Cookie directive. They are two very different laws. GDPR is concerned with personally identifiable data and data protection, the cookie laws are concerned with tracking users online. GDPR applies to all data (not just websites), the cookie laws deal with what websites can do. They are not at all the same thing. The popups you see tend to be for the cookie law, because GDPR doesn't require anything like that. Both do require consent (opt-in) though, but both also have exemptions for data and cookies required to provide the service.
