I know half of HN hates Telegram and I like it less than when I started moving (and to my defense that was before WhatsApp improved their crypto from close to nothing to state-of-the-art.)
It has served us well but I don't like the constant bragging combined with breaking a number of best practices and I'm looking for alternatives now and might start moving users to a system that stresses me less sometime during the next year. Alternatives right now are signal, matrix etc.
(Did I regret moving away from WhatsApp after they fixed their crypto? Not at all: they still uploaded all chats and sneakily tried to use all WhatsApp data to feed their spam cannon.
Matrix is certainly worth taking a look at. I always liked how whatsapp and telegram mobile apps were very snappy. That's something that is going to be fixed in riot quite soon, apparently.
I don’t know about chat, but i’m quite sure they didn’t just try to use WhatsApp metadata, but rather put it to full use. I believe they even admitted so.
