It’d be quite the three ring circus to see France attempt to arrest Mark Zuckerberg or Larry Page. I’m 100% sure the US would flat out refuse to extradite such people, they might as well try to arrest John Roberts.
Doesn't matter that much if the US doesn't extradite them ( of course they won't, like France doesn't Polanski), they still have to avoid every EU member and close to France country, which can be pretty limiting.
