Business Insider:

In early February, Google announced that Assistant would work with its home security and alarm system, Nest Secure. The problem: Users didn’t know a microphone existed on their Nest security devices to begin with. On Tuesday, a Google representative told Business Insider the company had made an “error.”

“The on-device microphone was never intended to be a secret and should have been listed in the tech specs,” the person said. “That was an error on our part.”

What — did they “forget” they had put a microphone in these things?
