If you can have encrypted group chats, then clearly you must be able to join and synchronize an encrypted conversation with more than one device. Encrypted group chats exist in Signal and other applications, so clearly this is possible. (There are other mechanisms (to have encrypted group chats) than just pretending each device is a separate chat member, but I thought this was an intuitive way to understand how that could securely work.) Regarding giving metadata to governments: I want that. If someone commits a crime, then sure the government should be able to request the data on this person (it might exonerate them or implicate them, though of course it's only ever supportive and never a sole reason to convict). The governments that most people here chose are not evil. Dragnet surveillance is not good, but individual data requests for individual persons after a judge approved it? That makes sense to me, at least from the perspective of the Netherlands. If Telegram doesn't comply with these requests (and that's a big if, because I heard otherwise), it would be a reason why democratic country might rightfully ban Telegram. But anyway that's perhaps a more political discussion rather than technical. Telegram has the data, just like every other centralized platform either collects or can be forced to collect it.
