Are you aware it’s the case in the US too? I don’t see what is supposed to be bad or terrifying here. French regulators (why the scare quotes?) entire reason d‘être is what you frame as suspicious, but it’s pretty standard, the state governs the infrastructure in its territory
US regulators don't order ISPs to block websites.
The FBI will occasionally seize a domain, but only after a court order.
Also notice that the FBI has no jurisdiction over foreign domains. It happens that the .com (in addition to .us) registry is in the US, but e.g. the .ru registry is in Russia and not under the jurisdiction of US courts.
This is a red herring.
We're not arguing about whether it is standard for governments to attempt to exercise maximal control.
We're arguing about whether governments executing censorship regimes via ISPs (like the Chinese Communist Party) without any balanced legal proceedings is a good thing.
And no, it does not happen like that in the US.
