Rolls Royce makes arguably the best product in their market. How many they sell doesn't have anything to do with the quality of what they make, or how many lawyers they employ or how many patents they control.
I guess inside the "ecosystem", "quality" is whatever Apple is doing the best at today.

No, Apple tends to actually have the highest quality products. Apple also consistently rates highest for consumer satisfaction and support. So Apple isn't one of these companies making cheap products on a slim margin, suing because they need to pad the balance books or slow down the competition so they can catch up.
The simplest definition of "quality" is whatever the public is willing to pay the most for. Apple doesn't sell $300 laptops, but it makes more money selling laptops than anyone else does - meaning either that they sell devices on the basis of glitz, or that they sell devices which perform well and remain valuable when used. I didn't buy an expensive model of Mac, but years after I bought it, PC users who see it are struck by it.
