What the hell makes you think they wouldn't exploit it _regardless_of they thought they could get away with it? Diamonds are a limited but abundant resource and look how much the industry has inflated their price. Enough that if Russia decided to flood the market their entire bullshit business model would collapse. So if Netflix could somehow open enough of the popcorn industry then they would absolutely charge more for it. Any company would. That's how capitalism is designed to work.
As soon as you have bought the popcorn/ diamonds no one cares who is going to consume them as a movie snack. So you always will be allowed to share your popcorn/ diamonds with your peers without legal repercussions, which is my point.
You are not wrong with the things you said. But I talked about virtual and real goods and the attached exploitation rules. And you talked about marketing and supply/ demand rules. And I fail to get the connection between those.
Is it (the lack of) morality and opportunism on the supplier's side? Help?
