Privacy is a spectrum
Carrier-based calls/texts that lack end-to-end encryption is at the wrong end of the spectrum.
I agree. I use an unplugged phone btw If the other party isnt using one, Im back to the wrong end of the spectrum. Can I trust signal? Can I trust telegram? I dunno. Fortunately my privacy concerns are trivial and I just dont want big tech marketing me so not a huge deal to me but I hear ya unplugged.com
Unplugged are scammers: https://x.com/GrapheneOS/status/1808161048194671006
Signal is end-to-end encrypted by default, Telegram only has optional secret chats for 1:1 chats. They can access most of the messages.
