Yeah, it seems that everything has an imperfection, unfortunately. Just gotta choose one. I'd jump on Signal if they remove the phone number, but like you I think it's the shiniest of the bunch. I just want media with captions, uncompressed uploads, the ability to search messages, full e2ee for calls and messages, the ability to conference call, secure message migration/sync to a new client, emoji/rich text and markdown format support, by a company that promises not to access its users' messages, location or other identifying information.
