I was also surprised by the physical masks. It seems they are intended to 'encrypt your face' which gives me the impression it should make you unidentifiable.

When peacefully protesting, I can't imagine why you would need to hide your face.

If not peacefully protesting and/or looting, such a mask has use for criminals, but I can't imagine that's the intention of Signal.

I think in free, democratic countries, you shouldn't be allowed to hide your face, so you can be held accountable for your deeds.

In non-free countries I can imagine you would need to hide your identity, but would Signal be able to distribute them there?

Questions, questions ;)
