This is a Swiss company offering services to French users. Although Switzerland is not an EU member, it is a party to the European Free Trade Area (EFTA) and through this, the Swiss government would likely be required to help enforce French rulings against their companies.

If I operate a bookstore physically in switzerland and a few of the books I sell are illegal in france I'm not required to check passports or whatever, am I? I can just sell books to whoever (subject to swiss law) and if a french national illegally imports one to france that's a problem for customs or the local police or whoever (analogously the french ISPs) to deal with. Not me, the swiss bookstore operator.
Now consider if I were handing out pamphlets for free rather than selling anything. At that point I'm arguably not even doing business because no money has changed hands.
I realize that the current legal reality might be that quad9 needs to block french users in practice but the entire thing is a farce if you stop and think about it.
