Once you pay who? Money going to the wrong people is far worse for "creators" in the long run than if you had just copied it. Every digital industry has proven the argument billions of times over. If you're going to bother feeling guilt, aim it at actual injustice.

You’re adding a lot of dimensions to the act of buying something than I care about. I’m not trying to fight injustice when I buy most things, I’m just following the realistic legal requirements to use the thing.
