I think the implication was that some asshole can obtain photos of you sleeping by opening the curtains and switching on the lights in the middle of the night. A nuisance, sure, but also a massive violation of privacy.
So, somebody is going to set up shop across the way, in what is probably another commercial building, commit a couple of crimes, all to take a picture of some random, likely unidentifiable person sleeping in a hotel bed?
Personally, I'm not very worried about that.
I mean, it's not like there aren't easier attack vectors for creeping on people in hotel rooms if you were so inclined.
Or a camera equipped drone.
It made Tron look technically accurate.
