You might have uploaded your name and face willingly to Facebook in order to set up your profile, but without proper safeguards and legislation, the data might be used to train an AI model to use your face to identify your relations with other user using photos, which they also willingly upload, to power features such as people you might know and of course, advertising. The data might also be sold or transferred to third-parities like Cambridge Analytica for political advertising or government agencies for "national security" -- all without your explicit consent.

It is true that it does not matter if a piece of data is stored in either side of the Atlantic, but this is not a engineering problem about data locality and latency. As someone who spent months working on a global distributed GDPR-compliance identity store, my life will be much easier if the problem can simply be solved by paying a slightly higher inter-region data transfer fee.

Unfortunately, US and EU here are not referring to cloud regions, but as jurisdictions because different laws on data protection apply. None of us likes this kind of complexity, but "power move" would be an overly-simplified abstraction of this problem.
