Note that telegram chats are not e2e encrypted by default.

And that it uses a proprietary encryption protocol, "MTProto", which has been repeatedly found to have vulnerabilities, like every other self-made encryption scheme.

Now add in the fact that it's a UAE company...

> which has been repeatedly found to have vulnerabilities

No, it has not. Recent research by seasoned encryption experts found minor bugs in realization, mostly around messages order. @see https://ethz.ch/en/news-and-events/eth-news/news/2021/07/fou...

You're misusing the term proprietary here.

Telegram's protocol might be custom, but it's well described and there are open source client implementations.

Whatsapp is totally closed and non-interoperable.

And whatsapp is made by an US company, that's an assurance for data collection and massive surveillance.

> Now add in the fact that it's a UAE company

I don't know why you keep saying that. They have servers and offices distributed in different countries, but IIRC most of the team including the founder and CEO are Russian. They say the distribution is so that no single jurisdiction can force them to do too much.

As if we are supposed to trust US or any other countries. Lol

Do not roll your own crypto is meant for software engineers, not a team of professional cryptologists.

Except who the hell even use E2EE on Telegram?

Fair enough, not me. But it's there and verified if you want it.

Yeah it's here, but it doesn't sync between devices, there is no group chat support, etc. While marketing trying to sell Telegram as good privacy by default.

Some people use secrets chats if you want to hide something, they have the auto destruction of messages and chat way before it was implemented on WhatsApp.

You can keep it for personal chats. Also it has no contents revewled in notifications so apps with notification access cancan't steal it.
