In the world if matter, things have copies and we can count them. In the world of knowledge there's no such concept and it lives by different rules. RIAA and other luddites try to turn ideas into stones to sell them.
so things that have low cost of materials / low cost of delivery, but high cost of skills required shouldn't be expensive? or what?
I don't understand how is this even relevant that software can be distributed very cheaply.
Creating software, or even better - the game requires significant investment and risk, so I don't understand how anyone would want to act as if that pirating was OK.
I'd argue that software isn't built, but discovered and selling the same knowledge of how to sail the discovered island is a challenge, as we know. SaaS is essentially hiding that knowledge and selling bits of derived knowledge specific to each customer. SaaS doesn't attempt to sell the same knowledge twice. Otoh, the movies and music industry hasn't figured out this derived knowledge trick, so it struggles.
Imagine if someone told you "Oh, that physical book you bought, with the pages and the words in it? Yeah, actually what we sold you was a license to a book." It's nonsense. We only played along in the digital realm because it was the only way for commercial digital artifacts to exist given the greater ease of making perfect copies of digital artifacts compared to physical artifacts like books.
That said, XaaS is now making that social construct physically real. It's still hamstringing one of the best things about digital artifacts, but at least it's honest now.
As a rule, you don't buy software, you buy a license to use it. So effectively you're stealing that license and the income it would generate for the creator.
Music and other media are the same. You don't pay for the bits, you pay for a license to access and enjoy those bits.
Which is why it doesn't matter if the delivery system is paper tape, carrier pigeon, optical media, or instant download from a server.
