There is a Dutch news article about GrapheneOS on security.nl
It says; (translated to English)
"GrapheneOS Removes Servers from France: 'Country Not Safe for Open Source'
The developers of the GrapheneOS operating system have removed their servers from France. According to the developers, the country is not safe for open-source projects and the authorities allegedly want to add a backdoor. They also criticized reporting by French media. GrapheneOS announced its departure from France through X. Earlier, Le Parisien and Le Figaro reported that phones running GrapheneOS are a "secret weapon" for drug dealers, basing their findings on information from the French government, according to the developers. The same French government wants people to believe that GrapheneOS and Signal are responsible for crime in the country, the developers further claim.
The French newspaper Numerama subsequently published two articles about GrapheneOS, one of which the operating system's developers described as a "defamatory hit piece." "A false narrative is being spread about GrapheneOS, claiming that we are closing our operations in France because of the actions of two newspapers. This is completely false. Even if both newspapers and the French media as a whole had sided with us against the prejudice against us, we would still leave."
According to the GrapheneOS developers, France is no longer a safe country for open-source projects, and government agencies want extensive access. "They want backdoors in encryption and also for gaining access to devices. Secure devices and services will soon no longer be permitted." The developers add that they even no longer want to use French hosting providers for hosting their website. The developers also claim that there is an active attempt to thwart an experimental GrapheneOS release for Pixel 10 devices and that the development team is the target of all sorts of personal attacks."
