Summarized translation:

Following the propaganda of the ministry of interior, several articles were published in press about GrapheneOS, which is described as a solution for criminals because it allows to hide things.

La Quadrature du Net [similar to the FSF with regard to defending users' rights] argues that the purpose is of course not cybercrime, but to secure and protect the privacy of its users.

The head of the anticybercrime brigade of Paris threatens of suing the developers of GrapheneOS if connections with organized crime were to be found.

The government has repeatedly tried to extend cyber-surveillance previously. They are trying to use a law designed to fight drug traffickers in order to enforce backdoors in services that use cryptography, such as Signal or WhatsApp, without any success for the moment.

So, it's a threat before having a proof. They also mention the arrest of Pavel Durov, who was arrested because Telegram failed to answer legal requests, which was then constructed as complicity with criminals using Telegram, but that's obviously a very different case.

But of course, if they succeed in forcing backdoors, criminals will just use other ways to communicate (doesn't matter if they are legal or not because, well, they are criminals...) or tricks; for instance, back in the day when (analog) phone calls could be wiretapped, they were already using code words. They could use e.g. steganography tomorrow.

But we will be left with backdoors that are an unacceptable compromise on security and privacy. This is a recipe for dystopia considering that far-right parties are getting stronger in Europe, including France.
