Telegram at least offers end-to-end encrypted “Secret Chats”

These are worse compared to signal chats. In signal, after login on say phone+ desktop, you'll have access to messages in secret chats on both devices(wish it would sync even if login on second device was later), on tg you are limited to only one

Nope.

HN doesn’t like hearing this, but e2e encryption is kind of an anti-feature for the vast majority of users. The usability tradeoff is real, and most folks don’t care at all about the privacy/security side.

Thing is, both can be achieved, but tg doesn't want to implement e2ee by default and signal doesn't want to implement a proper sync mechanism bc of some extra security(imo it's bs, extra security can be achieved with a proper implementation)
