That's why you pay to buy the toaster...

If I took your toasters of the back of a truck, added "Powered by MagicMoonlight" on the side and started getting people to pay me for them, I'd imagine you'd be displeased. You built the toaster and now I'm making all the money from it. I'll tell you that I'm the one covering all the marketing budget and the electricity bill so it's not even affecting you, but is that really the case?
