> It's already common to see criminals and dissidents get busted because they think that turning a phone off stops it from reporting location data.
That’s an incredible claim to make with no source. It seems unreasonable to suspect Apple and google would allow some chips they don’t access to battery even when powered off.
Well if you can make claims without a source and say the tech is secret..you can claim literally anything? I have a startup that builds a machine that can complete medical tests from a single drop of blood. The tech is a secret though.
