Do you mean that I, an EU citizen am being granted some special privilege from EU leadership to send my data to the US?
I say temporary because it keeps being shot down in court for lax privacy protections and the EU keeps refloating it under a different name for economic reasons. Before this name it was called safe harbor and after that it was privacy shield.
I mean, sometimes the government steps in when you willingly try to hand over something on your own will, such as very strict rules around organ donation, I can't simply decide to give my organs to some random person for arbitrary reasons even if I really want to. But I'm not sure if data should be the same category where the government steps in and says "no you can't upload your personal data to an American website"
It's all about jurisdiction. Do business in Country X? Then you need to follow Country X's laws.
Same as if you go on vacation to County Y. If you do something that is illegal in Country Y while you are there, even if it's legal in your home country, you still broke the law in Country Y and will have to face the consequences.
Where is the HQ of the company?
Where does the company operate?
What country is the individual user in?
What country do the servers and data reside in?
Ditto for service vendors who also deal with user data.
Even within the EU, this is a mess and companies would rather use a simple heuristic like put all servers and store all data for EU users in the most restrictive country (I’ve heard Germany).
If outside EU, then they need to accept EU jurisdiction and notify who is representative plenipotentiary (== can make decisions and take liability on behalf of the company).
> Where does the company operate?
Geography mostly doesn't matter as long as they interact with EU people. Because people are more important.
> What country is the individual user in?
Any EU (or EEA) country.
> What country do the servers and data reside in?
Again, doesn't matter, because people > servers.
It's almost like if bureaucrats who are writing regulations are experienced in writing regulations in such a way they can't be circumvented.
EDIT TO ADD:
From OpenAI privacy policy:

If it was easier or more cost-effective for these companies not to have a foot in the EU they wouldn't bother, but they do.
Americans often seem to have the view that lawmakers are bumbling buffoons who just make up laws on the spot with no thought given to loop holes or consequences. That might be how they do it over there, but it's not really how it works here.
EU companies are required to act in compliance with the GDPR. This includes all sensitive data that is transfered to business partners.
They must make sure that all partners handle the (sensitive part of the) transfered data in a GDPR compliant way.
So: No law is overriden. But in order to do business with EU companies, US companies "must" offer to treat the data accordingly.
As a result, this means EU companies can not transfer sensitive data to US companies. (Since the president of the US has in principle the right to order any US company to turn over their data.)
But in practice, usually no one cares. Unless someone does and then you might be in trouble.
