Just as Apple lost when they tried to sue Microsoft. This just proves your MacPropaganda piece is - say it with me - MacPropaganda and has little connection with reality. Xerox was pissed at Apple and Apple did not license the GUI.
The judge disagreed with you. He dismissed all of their claims except for one that wanted the court to recognize that Xerox owned the rights to the Star techology... unrelated to Macintosh and which Apple did not contest. Xerox received millions of dollars in stock for what Apple used... in advance.
. . . It was only when they brought him to see the work being done at Xerox PARC on the Alto in December 1979 that Jobs decided the future was in such graphics-intensive, icon-friendly computers, and supported the competing Apple Lisa and Apple Macintosh teams. Over the objections of some PARC researchers, many of whom (such as Larry Tesler) ended up working at Apple, Xerox granted Apple engineers 3 days of access to the PARC facilities in return for selling them one million dollars in pre-IPO Apple stock (approximately $18mil. net). The Lisa debuted in January 1983 at $10,000. Once again, Apple had introduced a product that was ahead of its time, but far too expensive (the company would continue to follow this pattern for the next few years), and Apple again failed to capture the business market. The Lisa was discontinued in 1986.

Try doing a Google search for Xerox, Apple, and lawsuit... and see how hard it is to find anything at all on the subject. Most of the commentary is related to the Apple v. Microsoft suit and the effect of the Xerox v. Apple suit and ignores the fact that the judge disagreed and tossed the Xerox case.
I will agree they did not "license" the GUI... but they paid for the ideas they got and Xerox did well on the pre-IPO stock they got.
