But that does not address the fact that according to the GDPR in its current state, a company such as Google should not have the authority to process EU citizen's data unless it's fully compliant with GDPR. How they're going to enforce that, I have no idea. Now if I've understood this correctly, this means that if a foreign company is fully complaint with this new law, we would have much greater access to data that is being collected, and we also have the power to request the removal of said data. The US government might still collect all those incoming data before it has the chance to be removed, but having a law such as GDPR being enforced would be a huge step forward.
