That's just ridiculous. First, you assume that people buy Macs for the OS rather than the the beautiful hardware. Even if it's true, where's the evidence?
And why does it matter that Apple ties the OS to the hardware? Still not illegal because the according to your link, it's illegal if it's a tying of unrelated products. OSX and Mac hardware happen to be very related.
Apple positions itself more as a luxury brand with a somewhat higher price point (arguable) and the consumers are allowed to choose what they want. And they have spoken.
