Your link doesn't work, requires a paid subscription to the New York Times which I suppose you must own. But I'll admit that I may have gotten confused when posting the Unix chart from 2000, apparently Apple's products weren't based on Unix at that point.
The bigger issue still remains, in the overall *nix family, Linux has just passed Apple, and the lead is expected to grow. Being the owner of several Apple systems throughout their history myself, I'm extremely disapointed to know that instead of folks the world over purchasing a true US Unix product from an American IT company like Apple, more and more are just going to be downloading some free copy of Linux instead. If you'd rather argue that Apple is second place to Linux instead of Sun, I could really care less. They both are losing to Linux.
