> WhatsApp does not protect metadata the way that Signal does. Signal knows nothing about who you are.
This isn't strictly true though, no? Signal knows your mobile phone number.
I appreciate that this is for facilitating usability, but its still a piece of metadata that can specifically be used to identify you - and signal knows it. You cant even use signal without verifying a mobile phone number AFAIK.
They really shouldnt be making false statements like this. It undermines their (otherwise admirable) position.
I think this means, assuming it’s not a burner SIM bought with cash, that someone could “only” identify you were a signal user. They wouldn’t be able to see your social graph , who you contacted and when, from where, what was said, what groups you were in.
I also thought I’d read on HN recently that they were looking at making this optional in the future but don’t quote me on that !
