With the proliferation of actual illegal material on Signal I can at least understand Durov being arrested, even if I’m undecided on whether I agree with it. But why in the heck would they reasonably go after Rumble? It’s just American conservative YouTube. I haven’t heard of any actual illegal/illicit material (political opinion pieces don’t count, that is in fact free speech) at all connected to Rumble, or at least no worse in proportion to YouTube or Twitch.
EDIT: And as far as I’m aware, Rumble does have moderation, it’s just not as strict as YouTube’s at least when it comes to expression of opinion. I wouldn’t doubt they have a policy in place for that kind of illegal/illicit material to at least be taken down. Perhaps France was threatening them because they wouldn’t cooperate by handing over user data after that? /shrug
