Nowadays, a majority of apps require you to sign up with your email or even worse your phone number. If you have a phone number attached to your name, meaning you went to a cell service/phone provider, and you gave them your ID, then no matter what app you use, no matter how private it says it is, it is not private. There is NO exception to this. Your identity is instantly tied to that account.
Signal is not private. I recommend Simplex or another peer to peer onion messaging app. They don’t require email or phone number. So as long as you protect your IP you are anonymous
It is certainly a lack of security. I wanted to emphasize how it’s also a problem for privacy. People in the thread are now having an imaginary argument about anonymity, even though this has never been something I’ve been confused about. However, it is something that one of the users pulled up, and now they all are harping on it over and over.
Since my phone number is one of my personal belongings, although abstract, if I hide it from you, it is private. If I reveal it to you, it is not. Since it is associated with me, revealing it to you lowers my privacy, as it is one more thing revealed that belongs to me.
These fools can’t even comprehend this, literally.
