Ah, this is so cute.
Copyright is an artificial, government backed monopoly on the publication and distribution of a "protected" work .
You are not assured of any money whatsoever. Ever. The LGP edition of Ballistics from Grin, SE proved that out to me. Even if there wasn't the 5-10k units of pirated versions on The Pirate Bay out there, the thing probably wouldn't have been much more sold for Linux.
Not because of the Linux market's "small". I know better. You appear to not.
Not because of the piracy, though that didn't help. I know better. You appear to not.
It was because we couldn't price the thing to what the market, at that time, could willingly bear. People would point to the bargain-bin priced Windows version and ask why they should spend $40 when it's available for $5, with the understanding that it only ran so-so under WINE. Seriously.
People will pay you what they believe it is worth. I know this because I saw some small, but real amounts of money from my participation with the Humble Indie Bundle #2. No DRM. No BS. Pay me what you thought this was worth or donate it all to charity- or somewhere in-between. It's my right and desire to control how it's shipped, copied, etc. within the limits allowed me by law for things, relative to work for hire, etc. that I agree to. But, to say what you said? X-D
Do you have IP, which is to say, creative works protected by Copyright or Patent? I. Do. As a rights holder, I can tell you that the rights are only worth the amount you are legally able to pursue enforcement of the same. Unless you're a big, big corporation, there's some hard limits on your rights there- because you don't have the finances and all to defend the same. Legally speaking, your only position (hint: Morality doesn't even factor into this...) is to not use the works in question. Morally? You should abide by the law so long as it's not wrong/evil. DMCA? Probably wrong/evil. Copyright? You have fair use exemptions, which in many cases people "stealing" it all fall under. And, it's not theft. It's infringing on your right to control publication and distribution. Again...no assurances of money. No assurances of people doing the legally right thing...ever.
Morality? This varies between persons and what faiths and beliefs they hold. I don't hold yours...why should I let you dictate to me that? (Oh, WAIT... I don't ,)
