The question of what should be done in cases of copyright infringement is the only one that can really be usefully discussed, which is probably why most people are addressing that instead. Should people copy photographs for commercial purposes? Of course not. End of discussion, not much more to say. This seems to come up fairly often - an article making a moral argument that copying is wrong, followed by comments saying "Yeah, but it still happens, so you should do X", followed by replies saying "no, but you don't understand, it's wrong!" Strangely enough, this seems to come up mostly in the context of music (or, in this case, photography). I haven't seen many software blogs making a purely moral argument as opposed to a practical discussion of what to do about it.
