Requiring a Sim is not a backdoor and does not enable "spying". I does allow knowing who is on the platform, who talks to who, when, and probably some more metadata issues. But its not a backdoor
It's a huge security vulnerability that Signal devs refuse to fix.
Not more than using username and password. Phone number is a security risk be cause you can get Sim swapped. If you have the registration password it's safe, but a government can request a bypass. However, if you had no phone number and used username and password, governments could still request a bypass
No, phone number is a risk because a phone number uniquely identifies a person. You need a government ID to get a phone number.
Then it's a privacy issue. Not security
privacy and security are one and the same. you can't separate them, it makes no sense.
VERY different things.
Bitcoin is secure but not private.

I'm not really sure what you want to say with that. I always loved that comic although I always thought that my reason for wanting high security is not to be 100% protected from any thread. If you show up with a wrench I'm going to give you my btc seed before you even hit me. But I'll know. If something has low security. It can happen without my consent and without me knowing
Signal's fancy E2E encryption doesn't matter if the government can force you to unlock your phone.
What matters is that everything in Signal is based on a phone numbers. Which means it can be traced back to an individual.
Signal is insecure exactly for this reason.
OK. You do you. The rest of us define security, privacy and anonymity in a whole other way.
If you keep thinking about it, you will keep finding cases where they (all 3) are not the same
