To be fair, they say:

> Since everything runs locally on the device without sending either audio or fingerprints to a server, the privacy of the user is respected and the whole system can run in airplane mode.

This is far more respectful of user privacy than we usually see from Google. I, for one, am impressed.

What does this have to do with the comment you replied to?

A complaint about marketing ("get us to buy more"), on an article about always-on audio processing in a phone, implies a concern about privacy-invading user tracking. I was pointing out that (on the face of it, at least) this doesn't seem to do that.
