This understanding is part of why Gruber often seems like an Apple apologist. Even when he disagrees with Apple' decisions, he can generally give a good explanation of why the decision was made and why Steve and Tim and company probably think it is the right one. And of course, when he is writing from the point of view of Apple Inc., the primary question is always "What is best for Apple?"
(This also explains why I hate Gruber's writing about competiting companies like Microsoft and Google. I don't think he understands how those companies think and work at all, so his commentary on them totally lacks that insight and usefulness.)
