Does Telegram use E2E encryption by default now, yes or no?
For most people the fact that it does not makes it useful. It goves you good multi device support similar to facebook messenger.
Wire [1] (which I discovered a few months ago) is a platform that has end-to-end encryption, multi-platform support and multi-device sync. It also has text chats, voice calls, video calls, doodling, etc. The UX still needs a lot of improvement (compared to Telegram).
