I am oversimplifying here but: * install device that is designed to listen to speech in the house * the device is connected to internet * the device is capable of contacting other internet peers/services/hosts * the device knows a bit about its owner's internet presence such as contacts * the device is equipped with simple conversational user interface based on fuzzy human speech-command detection These basically bou…
We must not forget another critical component of all this: these always-on listening devices run on proprietary (nonfree, user-subjugating) software. Therefore the user has no permission to: inspect what it does, modify it to do only what the user wants (or, since most computer users aren't programmers, get someone technical they trust to perform such modifications for them), run the modified software in their device, and distribute copies of the improved software to help their community.
If these devices ran on free software (software that respected the user's freedom to run, inspect, modify, and share) the more technical among us could help them. But as it is even the most technically-minded willing person cannot legally do this work to help them.
As Eben Moglen reminded us after the Snowden revelations came out: It's critical that we don't fall into the trap of saying something akin to 'those kids take too many darn pictures' like concluding that we just can't have these devices or their services at all. We can have all of their alleged conveniences but only if we have free software implementations.
