If that doesn't spook you away from the phone, not even the price will.
Just weird. Except, let me ask this question.
How much would a huge global database of recognizable facial biometrics be worth to ..... someone?
If the money offered were right, could even Apple resist? Apple would probably accept payment in Bitcoin. And guess what, you gave them that info for free. Oh, except for the initial investment in the phone itself.
Really, Apple should have to pay you to get the ability to recognize your face anywhere, but folk are going to give it to them for nothing, laughing foolishly while they do it and oohing and aahing over how cool the tech is.
Way, way too far. I'd keep my dumb phone, thanks.
