> if I take a photograph of you out in the public and sell the photo for $1 million, would you expect compensation?
I mean I wouldn't expect it, but I think I'd be pretty annoyed if you didn't ask permission and then made a bunch of money off my image. It's easy to find stories from the subjects of famous photographs who feel like they've been exploited. Just off the top of my head there's Afghan Girl, the kid from the Nirvana album, Harvard's collection of photos of enslaved people, and Henrietta Lacks is sort of a similar case.
> if someone compiles a list of the best restaurants in the world and sells that list, do you think the restaurants should be compensated?
No, but here's a better example: you make friends with a bunch of food critics, collect their thoughts and opinions and favorite secret spots, and then publish a book based on that stuff without ever telling them what you were doing or compensating or crediting them.
I'll give a concrete example: I was rock climbing recently and met an old guy who was sort of the local expert, and he told me how some other non-locals had come in and kind of mined him for information about the area, all the routes, etc. and then published a guidebook without crediting him at all. He felt pretty upset and exploited by that, and I felt bad for buying the guidebook because I had assumed it was written by some local climbers and didn't realize they got most of their info from someone else.
It's not illegal, but it is unethical.
