Many other Nest products, such as the Smoke alarm, doorbell and camera have microphones too. I agree that not disclosing that one was bad, but realistically if you have a Nest home, you probably have at least one microphone somewhere. It also comes down to much you trust them that the microphone was disabled. If you don't, then you probably also shouldn't be carrying a smartphone with you either.
