OK, intent wasn't to cancel the sarcasm. Guess I just messed this one up.
However, being serious, where does parental responsibility enter the picture? One could reasonably think that part of that responsibility involves selecting the types of items around the house that the children have unsupervised access to. Just like you wouldn't leave sharp scissors around or exposed wiring, you probably shouldn't leave an always-on cloud-connected item with speakers, camera, and mic where kiddies below a safe age can interact with it without parental supervision. Especially when you know you've ticked the boxes that say any hacking is your problem, not Amazon or Google's, to use the bloody thing in the first place. And if you don't know you ticked those boxes, maybe it's time the lawyers pay a visit to the vendor HQ.
