This is straight up tinfoil hat. You really think they architected a whole new chip and had it fabricated just to data mine what songs you are listening to? You don’t think it would be easier to just send that data from Android? Apple, Sony and everybody else has custom chips for ANC and audio processing, it is in no way a generally solved problem.
It’s actually sad that shit comments that don’t even make logical sense get upvotes on here “because Google bad”.
