In the case of Durov and Telegram, these issues are *especially* muddy. Telegram bills itself as an encrypted messaging app, but that's only sort of true. Telegram does not encrypt its group-chats, and even the encryption in its person-to-person messaging facility is hard to use and of dubious quality.
This is relevant because France - among many other governments - has waged a decades-long war against encrypted messaging, which is a wholly illegitimate goal.
