It seems useless to me, at least regarding the cybersecurity aspect. Of course, it’s helpful when people ask for my contact information, and I don’t want to share my phone number or email address.
But they still require information that could be used to prove or be linked to my identity for registration, right? This means a hacker could still reveal your IP address, phone number, email, and your passcode. Likewise, the development team can access these as well.
I know I’m overly cautious about my privacy, but that’s just how I am.
My main complaint is that they officially prohibit 3rd party clients including 3rd party builds of their official ones. They also don’t have reproducible builds for their clients. It leaves the door wide open for inserting some telemetry via an update to completely bypass their otherwise good encryption and (lack of) data retention.
Would allowing third parties access to their server API just cause spammers to flood signal users.
