Not just see messages, but show you ads as well: https://news.ycombinator.com/item?id=25520200 Telegram's a down-right bad IM experience compared to WhatsApp despite Facebook's forced integration: You see ads and the chats aren't encrypted.
>bad IM experience compared to WhatsApp I'd say forcing me to type on a shitty tiny on-screen keyboard (or use a _browser_ while still keeping the network on my phone running) is such a terrible experience that literally everything else wins in comparison to this.
I think you do realise that WhatsApp uses E2E and there's no way to do it any more securely unless the messages always go through your phone; and so, I believe you have already made a choice to use insecure services because "convenience", but in the context of current discussion (privacy and security), WhatsApp comes out superior despite Facebook's involvement. And that's saying something.
