Vigorous discussion isn't an unqualified good. If it goes somewhere, sure. But discussions on HN of Apple's business activities seem rarely at best to do that. I don't understand why the light:heat ratio in this kind of thread is so low, and usually I keep my mouth shut about it, but today the urge to say something overmastered my self-discipline on the matter. I don't pretend that my comments here constitute any more of a contribution to worthwhile discourse than anyone else's do.
