I read their argument as "some people say it's immoral to run a hackintosh, but I think it's not immoral because Apple isn't providing their consumers with a valid alternative".
> Every Hackintosh continues to add momentum to that platform ecosystem, enriching it so that Apple can continue on more or less as they want.
I use Linux (and OpenBSD occasionally) these days, and I do so in part so that I can sometimes be the guy who sands off a rough corner or two. Even by using the platform and occasionally submitting bug reports, you’re enriching a platform that may be the last un-nerfed general purpose computing platform standing.
I don’t really care one way or the other about the stealing question, because this other argument against hackintoshes is more compelling to me.
In other words, there has to be some reason that they don't see it as stealing but do see it as a failure by Apple to meet the needs of it's consumers. That reason is the relationship between the two concepts and I don't understand what that relationship is.
