There should be a way to pay only the workers when you buy something. In that case, you could pay them but only after pirating and making sure you enjoy it. Since there is nothing like that, I think you should pay only content from small creators. Big creators already have plenty, and paying for anything else just gives money to greedy executives who then lower the quality of the content to make more money. Of course, if you have the means and don’t pay anything, you are just making sure there will be less of that content made in the future. It isn’t scalable; if everybody pirated content without paying a single cent, there would be no content made except by hobbyists who don’t want to make a living out of it.
Oh yeah I was thinking more along the lines of video games or movies where there are too many people creating it. For books, etc you can definitely donate.
