If curious get on one of the mentioned neighborhood apps, see how people use these devices: package theft, suspicious people/cars, vagrants/unstable folks, public disturbance (skaboarders scratching cars, etc.,) early hours canvassing by thieves, etc...
Show me one place where package theft is even mentioned on Ring's website or in their doc. Is isn't.
It naive to think that Amazon is worried about package theft and that's why they bought Ring. Too many other tech companies have signed up for the surveillance economy for that to be true.
What's the real reason?
As for why I would guess wanting better rates from turning bits to cash.
Shoppers do not care about package theft
Ultimately, the consumer only cares about what product he is getting and what price he has to pay. How the company juggles its losses or where they come from is of no interest to the product purchaser.
