Optional E2E encryption is effectively not encryption. The default encryption in transit is useless if you don't trust the server. The argument about convenience is ridiculous. Whatsapp provides better default encryption than Telegram. The (probably deliberate) flaw in Whatsapp encryption is the default backup method, but E2E encryption is enabled by default with no loss in convenience. Telegram is not encrypted by default, and their encryption scheme has been shown to have rookie level mistakes in it. Just because it's "preferred by activists" doesn't mean said activists have any idea about secure communications. I'm not saying that you should jump on Signal (or anything else). I'm saying Telegram is almost certainly broken. Maybe maliciously, maybe accidentally, but almost certainly. For reference, I don't use either Signal or Telegram anymore, but Telegram sets off so many alarms I'd steer clear of it.
