They have been for a long time, along with many others who would love to get to their position in the market. Apple chases profit like all other companies, they just oft have a better UI.
The first thing Jobs did when he came back to Apple was axe all the Mac-clones that were being built. The second thing they did was try their best to put all non-Apple Macintosh repair shops out of business, and then open the Apple Stores once they'd done so.
They haven't changed business models, they just now have a dominant market position to leverage. Frankly I think they learned a lot of their current tactics from MS, but they've never had everybody's best interests at heart, any more than MS or anyone else did.
