Every iPhone and Android that host Telegram is complicit. Every chip maker that supply these phones is complicit. Every miner that mines lithium that makes the batteries that goes into the phones is complicit. How far do these idiots want to push this?

It's not really about that, he isn't complying with what the empire wants him to do, that's the real reason.
It's not a simple case of non-compliance. I say it again, Telegram ecosystem is a deliberately designed honeypot, and thus, valuable resource for any government. He was aware French are formally after him, he had some vague intercourse with RU top just before the flight, and probably found out something. He already created and handed over one RU honeypot for internal use, VK, and thus, has connections with "siloviki" (you NEVER quit!). I would assume it's rather a deal than enforcement.
