Durov has been going hard against censorship because the pressure on Russians to switch to MAX might consign his own app to oblivion. But to call Durov “anti-Russia” when Telegram development and servers remained in Russia, is to ascribe to him a dissident status that he doesn’t actually deserve.
(Durov himself is known to regularly visit Russia, while denying he ever visits Russia. Telegram opened a Dubai office claiming that it was now a Dubai-headquartered company, but that was a mere legal formality; no one was actually there at that office, and journalists visiting it found that not even the building staff knew anything about Telegram. In practice, the company continues to exist out of Russia.)
