Google is not going to all of a sudden start recording you in your home without your knowledge, and then say 'hey look, you signed a contract'. That would be an obvious PR disaster, not an 'I forgot disaster'. If/when Google enables this tech, it think it will be clear enough. If not, then definitely would be time to raise a real fuss. "There seems no good reason to me that the specification summary can't say" - I agree with you there - however, I suggest that they mighn't have even have thought of it. That would be the prudent thing to do, but again, there's no established procedure for it. There probably was not even a legal review hint etc. because as I say, they were not using it. So it's questionable, weird, but not nefarious. What they will do, with your ostensible permission, with a signed T&C - is to me, far more nefarious.
