The most common French word is Pédopornographie. But my impression is the definition of that word under French law is narrower than many definitions of the English acronym “CSAM”. Canadian law is much broader, and so what’s legally pédopornographie (English “child pornogaphy”) in Canada is much closer to broad “CSAM” definitions

Which French law are you alleging they violated? Article 227-23 du Code pénal, or something else? And how exactly are you claiming they violated it?

Note the French authorities at this time are not accusing them of violating the law. An investigation is simply a concern or suspicion of a legal violation, not a formal accusation; one possible outcome of an investigation is a formal accusation, another is the conclusion that they (at least technically) didn’t violate the law after all. I don’t think the French legal process has reached a conclusion either way yet.
