The FBI is the primary party appearing to be in this investigation, and to the best of my knowledge are both of the US (govt), and are federal. (I'm not a US person so please correct me if I'm wrong.)

Isn't a simpler explanation that the FBI was co-opted in the same way as Adguard, rather than that the FBI is masterminding the scheme?

Are you sure ? They say in the article that they were not able to fing out who sent the email. Site was behind Cloudfare (so US).

France doesn't have a federal government, as it's not a federation.

Yes, I know that.

This article is specifically an article about an investigation by the FBI- US federal agents.

The article mentions the FBI investigation but is not about that. This article is about a pressure campaign, the letter Web Abuse Association Defense sent to adguard making threats under french law and adguard's investigation in response to that letter.

A French organization with an English name, writing in English? J'en doute.

It was exceptionally clear from reading their writing, they are NOT native English speakers.

It seems 57% of people in France can speak English, which I can easily believe:

No reason to doubt this is coming from a French person.

Very many European citizens speak English and it's the lingua franca* of the Internet.
