What the world needs, though, is a decent, private alternative to Snapchat--which a lot of very normal non-technical people use specifically with the goal of "privacy" as they don't want to give their phone number to random people they meet at parties or while doing online dating or on services such as TikTok--not WhatsApp, which is already end-to-end encrypted (with the same protocol!). Signal needs to remain a viable alternative to WhatsApp to "keep them honest", but doesn't need to fight them and should move on to their next challenge (as the goal shouldn't be "get everyone to use Signal", but instead should be "get everyone to use an end-to-end secure messaging app"). This all happens to firmly fall into the first camp, which you incorrectly label as "purists" :(. Even the people I talk to who want to organize protests and the such are harmed by everyone pushing Signal as their main threat is a cop getting a list of all of the phone numbers in a chat off of someone's phone, something Signal doesn't solve... but, ironically, Snapchat and Telegram do, for all of their other faults: we need an end-to-end encrypted Snapchat/Telegram _stat_.
