I never asked for an infinite window of software support, though. I merely want the features that I had when I bought the laptop, for as long as the OS supports my machine. The response is always "blame the third-parties" when apps break, but oftentimes the devs already made their money and moved on. The onus is on Apple to support their OS' software if they want to have my money.

Open-sourcing is one solution, but knowing Apple it's not a likely one. Their "we know best" mindset is why I quit dailying Macs entirely - it's not sustainable outside the mobile dev business. A computer that supports 32-bit binaries, OpenGL or x86 translation when you bought it should be able to retain that capability into the future. Anything less is planned obselecense, even if you want to argue there's a silver lining to introducing new tech. New tech should be competitive on-merits, not because it's competitor was forcibly mutilated.
