When a law is justly created and is not manifestly unjust itself, following the law is a moral imperative. There is no equivalent moral demand that one pay a lot for something given away for free.
That's debatable and you know it. You're in that debate right now!
I think what the majority thinks is pretty clear at this point. I don't see how this is much more different than other pay what you want things. I remember "free" gift wrapping things back when I had a Borders, run by people trying to raise donations for a school trip or something. Sure, I could just give them 1 cent or even nothing. They would lose money from giving me the wrapping paper, tape, the service (wrapping my stuff instead of someone else who would pay), etc. That's legal. I gave them a few dollars, though, so they have a profit for their fundraiser. It's worth the cost to me, and it's the right thing to do. It's not too much different for the Humble Bundle, is it?
