An overview of Signal’s long list of flaws (phone number id, Play service payments, centralized infrastructure, etc) and the history of The Signal Foundation of ignoring many of these issues.
Signal is disappointing. And I am tired of pretending that it’s not. I have been using and recommending Signal for longer than it existed. Signal just came out with a feature we have been waiting for for 8 years.
You see 8 years ago, the only flaw Signal had was that it required a phone number to register and find contacts. This was bad, because it meant you couldn’t get an anonymous Signal account, which meant you could get hacked or abused by anyone who knew your phone number. It was also easy for authoritarians to censor people’s access to Signal by denying phone registrations by country code.
The reason for the phone number requirement was to prevent spam. The primary function, was to use your phonebook to quickly onboard new users and send notifications whenever anyone in your contact list signed up on Signal. A very convenient Silicon Valley feature that allowed people to quickly connect with their friends and also let domestic abusers find out their victims are trying to contact a lawyer’s office over Signal.
Google private vs secure communications. Privacy is the company not sharing information about your communications. Legally this is nearly impossible for a corporate entity without anonymity. But they could just as easily keep the data about who you are talking to secured and thus your privacy protected. They are private commercially in that they don’t sell that information like most messaging apps, but they can’t refuse an order from a government entity and thus are not 100% private. Again anonymity is one method of keeping your data private, the other is to have 100% control over that data like if you self hosted the central server then Signal could be private while still not being anonymous.
So anonymity is the only legal say to be private, but it isn’t the only way to be private. They do keep your data private from data brokers, thus some privacy, but not 100%. Anonymity is much more difficult to accomplish while maintaining usability. Privacy is only difficult to accomplish while maintaining functionality because of legal obligations. So their policies are privacy oriented, but they can’t guarantee that without anonymity which they can’t do without loss of functionality.
What they can do, and do well, is security. Secure messages, security of metadata in motion, etc., but metadata at rest while secure, is not private from governments, only from corporations (currently, though this could change and is why people think they want anonymity not realizing they lose functionality.) Signal is secure, and as private as it can given the legal obligations, but it could change policies and decide not to keep your data private and then anonymity is needed which is what the OP is saying they need, but Signal has never said they will provide.
No u.
It isn’t, and they don’t.
They don’t have to, because they are 100% private. They don’t have information to share.
