That sounds like a lot of mental gymnastics to try to justify doing something that you are not legally supposed to. You call it a licensing dispute, to me it sounds more like a breach of contract. Even the article you excerpted acknowledges that the legal challenge to the EULA is a long shot. Certanily, being challenged in court is definitely not the same as being legally invalidated.

Speaking personally, I don't really care if people want to run OSX on non-Apple hardware. It doesn't effect my life one way or the other. However, I don't care for people's moral justifications for it. People use all kinds of rationalizations for piracy too- but unless you're willing to be the test case and challenge the EULA in court, don't try to pretend that it's perfectly legal.
