I’ve tried planting the seed a few times with people who voluntarily wiretap their own house with an Alexa. Each time they’ve picked it up and ran further with it, like “Oh I know! If I mention seat belt covers, suddenly amazon is recommending a bunch of seat belt covers in my home page!” No thoughts at all of doing anything with this conclusion.
I’ve also witnessed planting the seed working in plenty of other scenarios, just thought this particular fumble was common and particularly funny.
