>"The truth is: the Nest Cam is never "off" despite an effort by Nest and its parent Google to make it appear otherwise."
And this surprises anyone? I work on the EXPECTATION that equipment that uses cloud services outside my control, and is not open source, and always connected to the Internet is just that.... uncontrolled.
Even if it were "off", there is nothing to prevent it from being turned on remotely or being changed to do so with an automatic update. Promises made by companies mean almost nothing to me... if you can even understand them when it is followed by 10 pages of incomprehensible legal jargon.
And then there are the security risks that have nothing to do with the manufacturer. If it is connected, it can be compromised by someone.
There is a reason I don't have certain devices in my home. This stuff is going to get worse and worse. People should probably reflect on why one wants or needs everything to be connected to a third-party service or always connected to the Internet. Just because it seems "cool" doesn't mean it is a great idea or that there is no potential hidden cost.
