Said no one ever.

I guess that plays better than:

"Hey we at Amazon would really love to collect even more data traditionally considered private. Please pay us to run a drone inside your home so we can 3d map it and see what stuff you have so we can sell you even more stuff and tell our partners all about you.

We could not figure out how to make it quiet so we are going to say that it's loudness is a privacy guarantee giving you several seconds to stop having sex when you hear a high pitched wine in hallway.

If our spy drone catches you naked coming out of the shower we promise never to use the images it captures until of course one of our employees is found with a TB of them. Then we will apologize while feigning outrage and promise to put procedures in place to limit this type of thing until the next time it happens."
