Well if I understand correctly, he was exiled from Russia for refusing to censor anti-Russian information on Telegram.  Now he is arrested in France for refusing to censor pro-Russian information on telegram.  It sounds to me like he doesn't care about nation states, he only cares about privaacy and free speech.  So irrespective of who uses telegram for what, or whether or not telegram is or isn't good technology, clearly this guy is one of us and we should support defenders of free speech, and therefore we should be against the French government.

Of course if you are against all governments this is a no brainer.
