Not stealing - they pay for each and every license fair and square, increasing Apple's profits each sale.
Better for everyone - more choice.
As Apple takes up an increasing proportion of the market as figures show, it would be correct to treat this as an Anti-trust issue.
Funnily enough - it will even be better for the negative camp - as they will benefit from Apple having to have increased choice - and maybe changing their unarguable extortionate pricing in eg extra RAM.
It would be a win for all - even those against it.
Apple competes against Microsoft and provides a BETTER product because the hardware is a known quantity, designed TOGETHER with the software.
Remove that unique approach, make Apple into a mini-Microsoft selling OS software to "anyone," and see if Apple can beat Microsoft at their own game. Maybe they can, but so far Apple's success has been by taking a DIFFERENT approach from Microsoft.
Meanwhile, this "choice" you like would hurt consumers by reducing the quality of OS X. The additional testing time and additional development complexity would mean more bugs and slower innovation. OS X would gain new features slower as a result of what you're asking for.
Imagine if Apple had been making OS X for "any old random PC" from the start. Would we have gotten to where Leopard/Snow Leopard is as efficiently? No--and Microsoft is a living example. They HAVE to deal with and endless array of unpredictable hardware. Their products suffer as a result. (No, that's not their only problem I realize--but it's one they can't control or fix.)
Be careful what you ask for. Anyone who says that opening OS X to other manufacturers is ALL good for consumers is not thinking it through. It's good in some obvious ways, and it is ALSO bad in some important ways. You have to acknowledge both.
So what those critics really want is to take away some of OS X's advantages, and replace them with OTHER advantages. That's fine if that's what they want. I don't blame them for pushing for it if so. But what they want is something different from the Mac platform then. Maybe some other company can build a new platform like that--THAT would be real choice: don't transform OS X into something new and partly worse, but add new OS options. (Easier said than done.)
As for me, I don't want to lose those OS X advantages that would be lost by making OS X more like Windows in this way.
(Also--lots of companies charge high RAM prices. But not even Apple forces you to pay that. Get your Mac RAM anywhere you like. That's always been an option. And the option to buy other brands of computers remains as well.)
Just don't expect Apple to spend time and money HELPING you to buy non-Apple computers. Because supporting those non-Apple users would be a LOT of time and money Apple would have to spend.
