Isn't part of " Europeans are ought to be able to decide how they want to live their lives" that they have the choice of using products of US tech companies?
If my manager's manager's manager decides, for any number of reasons, to buy a product which is using US-based technology, then I don't reasonably have the option to "vote with my feet", but I do have a fallback called Regulation, which works its way all the way up the chain automatically.
