Security and privacy often overlap. e2e secures messages content from unwanted eyes. And therefore also benefits privacy of course.

You were talking about security, not about privacy.

Telegram and WhatsApp both use TLS - so in don’t see the advantage for Telegram there.

I’m not talking about privacy, if you read the first replies from this thread you will see I expose some examples how easy is to exploit WhatsApp, that’s a security issue, not a privacy issue.

But to be fair I shouldn’t have started to talk about e2e if your initial concern was exploit count and serivity. (Which I didn’t compare between the two messenger’s)

Remember you said: “like Telegram doesn’t encrypt most messages therefore by design is already not secure and user data is readable.”

And I replied to you that no one said Telegram was unsafe, there were no exploits or any security issues, while on WhatsApp, many issues have been found.

Returning to your initial phrase:

Security and privacy often overlap. e2e secures messages content from unwanted eyes. And therefore also benefits privacy of course.

“secures messages content from unwanted eyes” is called privacy. Stop mixing the two concepts.
