> If his rights to the IP had expired after 20 years then not only would Netflix been able to rip his work off for free, but he wouldn't have benefitted at all from the resurgence in popularity that his novels garnered.

Presumably in the same way that if you sell the mineral rights on a plot of land to someone else, and then they find oil or rubies there, it's thought of as fair that they get the money from that and you don't.

Or how if you sell someone a stock, and it goes up, they get the money from the appreciation and you don't.

Or how if your neighbor finds buried treasure on his land, and you find none on yours, he gets a big finder's fee and you don't get anything. (Indeed, in this case, there are commonly accusations of unfairness, but those tend to focus on the treatment of the neighbor being unfair. You deserved the nothing that you got.)

What's a scenario where this kind of event wouldn't be called fair?
