When IR remotes hit college campuses, the game was to shut off someone else's TV through an open door. There's even a one button remote from that era that shuts off any TV in sight [0]. Voice control is like IR on steroids.

It happens. I've been rickrolled by an acquaintance yelling "Alexa play never gonna give you up by rick astley" thru a screen window. Its gonna be a widespread cultural thing once Hollywood inevitably uses it in a movie or TV show as a joke. I don't watch that stuff, maybe that's where he got the idea it would be "funny" to team up with Alexa to rickroll me.
I find privacy anxiety to be much like electric car range anxiety. Once you have the product its not an issue, it drops to zero, but debate on the internet is extremely hot and heavy right before widespread adoption kicks off. Enormous amounts of toxic anxiety and paranoia bleeding out all over stuff that in practice after deployment just doesn't matter. In other online venues I've been worried about causing heart attacks by suggesting my next car will be electric, and this topic is about the same here.
