Neither is HN, should I stop using it too?

Btw, Telegram is E2E encrypted opt-in

HN doesn’t have direct/private messaging. There is no expectation of privacy in public comments.

Systems designed around direct messaging that don’t have e2ee should not be used; otherwise you normalize surveillance.

I would expect a public chat with 1k+ users to be considered public. Even when E2E encrypted, it just takes one person out of those 1k to leak the whole content - so what's the point?

I too advocate for privacy, but for public discussions E2E encryption would make sense only as a mean of certification (person holding the key really wrote the message)

It’s not the groupchat; it’s the DMs that occur in parallel. Telegram would be fine without e2ee if it had no DMs.

Or if the "DMs" were encrypted by default.

Not for group chats.
