Where ever they want to do business at. If they expect to be allowed to operate in France/the EU they will have to comply with legitimate French/EU warrants. No one is saying they can't fight it if there is a reason to.

>Can the USA kidnap the owners for non-compliance, can the Russians?

Jailing someone/holding a company in contempt that does business in your country for ignoring legal warrants isn't kidnapping. Trying to frame it that way is pretty silly and disingenuous.

What does it mean to "operate" in a country though? If I operate a service in the US and have no servers in Iran, no employees in Iran, no physical presence in Iran whatsoever, but Iranians are communicating with me over the global public internet, does that mean I have to comply with Iranian law? What about if its France and not Iran? What if these French/Iranian users are not only communicating with me, but also sending me money and/or cryptocurrency in exchange for that communication?

Personally I would contend that none of that counts as "operating" in France or Iran. You're operating entirely in the US, and it would be ridiculous for Iran or France to try to subject you to their laws just because people who live in their country are communicating with you or sending you money. (Though obviously those people are still subject to the laws of their respective countries in what they're allowed to do when interacting with you, just as you are subject to US law in your interactions with them.)

Of course, the fact that something is ridiculous doesn't prevent a sovereign country from trying to do it anyway. Iran can threaten to assassinate you for communicating with their citizens, and France can threaten to jail you if you ever travel to France or extradite you. Both of those threats are unjustified in my opinion and should not be supported or condoned by other countries (particularly not the US), but like I said; they're sovereign countries so we can't do much to stop them if they want to be unreasonable.
