Maybe I'm just paranoid, but it's only a matter of time until Amazon's data is leaked and sold on the black market. Correlate house layout, number of residents and their schedules, plus income bracket (from another source, possibly also from Amazon), and it's a blueprint for burglars looking for an easy score in an upper-middle class neighborhood.
People who rob upper-middle class homes are not going to do so because they have a house layout in advance. They're just going to rob the house. And anybody who goes to the lengths of buying Amazon data on the black market is not going to be interested in stealing people's laptops and jewelry.
I think that's a bit naïve, considering how common it is to see modern tech and basic/traditional crimes intersect - from ATM card cloning, to using Tor+cryptocurrencies for buying drugs, car key fob hacking, etc.
Sure the people who currently buy data on the black market won't all start robbing houses, and the people currently robbing houses won't all start buying illegal data to help their burgling.
But as long as the economics make sense (and it likely would - once someone has a bunch of useful data that they want to sell illegally, they'll lower the price until it is worth being bought by people), some burglars definitely will start adding more intelligence to their planning including using black market data leaks for picking houses to target and for how/when to rob them, what items to look for, etc.
And potentially you also get other people for whom burglary wasn't a feasible option before, but combined with this new tool might be. Personally I'm not going to become a burglar for ethical reasons, but for the sake of a hypothetical let's pretend that I have no ethics whatsoever and think that stealing is a fantastic idea as long as I can avoid getting caught. I still wouldn't rob houses, because it would seem like quite a risky way of making money, and with each big risk taken there's a fair chance of not even finding anything particularly valuable once you've broken into a house.
But if I could buy data leaks that I trusted which told me which houses to rob to find the best ROI items (high value, easy to carry, and maybe even located thanks to the camera of a robot vacuum), and also told me when people would be home and would be asleep.... well maybe my hypothetical no-ethics self would still find a better crime to commit, but it'd be a hell of a lot more tempting to become a burglar than without all that data!
Do you really think there haven't already been crimes committed that involves basic dumb theft but where the targets were chosen based off a leaked list of car purchases, or jewellery shop customers, or...? And not just in the era of digital data theft, go back a thousand years and I'd assume there were some "crimes of opportunity" committed not on a whim but thanks to planning enabled only by the studying of information they shouldn't have been in possession of.
You don't need to go to the black market. You can look up the property at the county (or whatever) clerk's office or look at satellite imagery and get a pretty good approximation.
A ton of things are public information to a greater or lesser degree whether you like it or not.
