How is it a poor decision? OS X generally has been designed to not need right clicking. And where it does, aka Xcode you can just do control click in most places.
I don't really see how this is a poor decision on apples part. For windows sure, right clicking abounds, though I'd argue that right there is the crux of the problem in general. The over reliance on right clicking in user interfaces I think isn't too far off from "magic track pad pawing motions like triple swipe etc...". But that last bits mostly my opinion on the matter.
My fundamental complaint is that Apple, as a company, prefers form over function. Avoiding right mouse clicks in the name of simplicity. Designing thin laptops instead of durable laptops. Restricting installation on iOS to just the App Store.
