I guess so. It's encrypted data sent over email from what i understand. Tbf i'd rather trust software built with protocols specifically built for secure and private messaging, and email is known to not be that.
The protocol doesn’t really matter when you send encrypted messages over it like Delta Chat. Signal is not private nor decentralized and SimpleX doesn’t have encrypted group chats last time I tried
You are confusing privacy with anonymity. You aren't anonymous because your user is linked to a phone number, but your communications are private due to how their encryption works.
On the location attack: it is a matter of configuration and your location will be as ambiguous as thousands of miles.
Precise language is important if you want to understand and communicate truth. It helps a lot to understand the difference between privacy and anonimity there is a scenario where a person doesn't care that an adversary knows their id, but does care about the content of their messages. In which case, differentiating tools that provide that particular service requires language to discuss it.
Yup that's why it seems great :) though i haven't heard of forks. I think i'll wait a little more till i switch to it, just to see if it gets itself in hot water. It's too early to tell
