Amazon and Google want "smart" gadgets to report all activity to them.

In other words, if you have a "smart" (read "spy") light bulb with that proposed feature, and tell an Amazon or Google listening device about it, thenceforth any time you switched it on or off no matter how, it would send a report to Amazon or Google.

Even today, the only way to make "smart" products safe is to ensure they cannot connect to anyone else's systems.
