It's not even original - people have been doing this independently since the services came out, and I'm pretty sure there were some adverts accidentally-not-accidentally tripping the behavior just a couple of months ago.
It was bone-headed. The best they could hope for was to vaguely amuse someone the first time the ad came up. But what about the second , third, or tenth time?
It's potentially a lot worse for Amazon/Google than it is for Burger King. I bet a lot of people will reconsider purchasing these devices based on just this one incident. Most people might not react as strongly but if this happened to me I'd immediately unplug the device and throw it away. Actually I might just go ahead and smash it to bits too. Just thinking about the possibility of it happening makes me quite angry.
Good foresight by Burger King to jump on this before anyone else. But I hope everyone stops doing this really soon too.
