Yes but it does have e2e if you “want” it and for 99.9% of people that’s enough. The other 0.1% who “need” it are more willing to learn/adapt to Signal/Wire/etc.

I use Signal with tech friends, and Telegram with family/non-tech friends. I feel like the latter using Telegram is still better than them using WhatsApp, so I’ll take what I can get.
