On that subject, I'm kind of surprised that it's been out for months and nobody's reverse-engineered it publicly yet.
Some people said that Nexus phones that default to encrypt local storage was user hostile as there was a perceptible performance penalty. I don't think that is the case. GNU and fsf want freedom for the user. I fully support the freedoms. However, I also think that users do not have a right to force their wishes on vendors.
I think it is fair to say if you don't like the options we give you then maybe you should fork the project and build it yourself.
We're already there. Can you read the Windows 10 telemetry?
