As it has aged, Apple (along with Steve Jobs) has grown increasingly psychotic.
(I try not to have too much to do with crazies - or their friends!

)
Apple's biggest problem is that it owes much of its greatness to the "shoulders of the giants" it stood on. The whole Mac "concept" was lifted from PARC research (for which I understand they paid $1); and their first truly stable OS came about when they scrapped their flaky
System in favor of a Unix derivative based on the Mach microkernal.
Not invented here (NIH) is anathema to the engineers in most technology companies. Apple turned that around, enbraced it, and ultimately based their entire company on it. Which just proves how smart they are, despite the fact they can be unbearably arrogant to deal with.
But like many companies who were in the right place at the right time, Apple is not happy about it. Because deep down inside, I suspect Apple Computer worries that it is a fake.
People who are afraid they will not be able to come up with their own new ideas are always protective of whatever 'products' they currently have. Much like bands who don't continue to develop and evolve. These are the so-called 'artists' who worry more about wringing every last penny out of their current CD than they do about writing their next one. And that's because they're horribly afraid they won't be able to do it again.
Apple is afraid.
Fear can be an excellent teacher and motivator. But it can also make us stupid, selfish and ugly. It all depends on the person or group.
