Why are you so shocked that people want to assert control over their medical data? This is the crux of the problem. You're being absolutely incredulous that someone have a say in data that is about them.
Other people exist and have rights. It's about time that people assert their rights over data that is absolutely consequential to their lives, instead of being tiny pawns of companies who treat them like a highschool science experiment with live ants.
You either trust my company with your data, or you don't.
The idea that storing your data, encrypted at rest, on spinning rust platters inside your country somehow makes it safer than storing that same data, encrypted at rest, on spinning rust platters inside my country, is bizarre to me.
But that's fine. I think giving you the choice makes tons of sense. I'm not saying France should have a law forcing all data to be kept in the US. I'm saying it's bonkers that I cannot offer a product in France that happens to store data and process data on a server in the US. Even with a waiver. French citizens do not have the right to let their health care information be stored on a server in a different country. (As I understood the laws, at least - perhaps our legal representatives were misinformed.)
If you want control over your medical data, then I'm sorry, none of the existing tooling does what you should actually want it to. It should be stored on systems you designate. Not on some lowest-bidder French server that has unknown security practices.
It's amazing to me that you're lecturing me about other people's rights, when you're literally denying French people the right to buy my product, unless I meet some ultimatums. I'm not denying them, you are.
And you talk about consequential to their lives? My product lowered costs and had better patient outcomes, and we couldn't sell it. Maybe try a different argument.
