Do you truly not understand the difference between a massive market like iOS and a niche market like OS X? Apple is in the portable device business. The Mac is a small and ever dwindling sideline. Giving away OS X would send one message and one message only - that the Mac is dying and can't compete. That's not a true message and it isn't one they'd want to sent out.
Do you think they do it for silly bragging rights, or to make it easy for developers to target a single operating system? They do, you know, make money off the sales in the App Store. OS X software sales through the App store are minuscule in comparison and most apps are compatible with multiple versions. It doesn't matter nearly as much to them if people update Mac OS right away. And it's a lot harder to get someone who thinks they paid $99 for their phone to spend another $10 than it is to get someone who spent $1000-2500 to spend another $20.
Apple, like any SANE company, does things that will benefit themselves the most. They couldn't care less about fanboy praise
We'll I guess apple has gone INSANE.....
