Re: It's the data harvesting
So you're arguing over the semantics of the word "copy"? Simply put a copy is the same or close to the original. MacOS was radically different from Xerox STAR (not least of which because it wasn't a pre-emptive multi-tasking system), and was the fruit of a lot of research by Apple into human/computer interaction and GUI design. Apple literally wrote the book on how to do much of that.
The best you could argue is that SOME ideas were copied from STAR, and that Xerox were paid for their use. To use the hated car analogy, at most Apple bought a STAR chassis, then created their own engine and bodywork to produce something quite different.
Microsoft likewise copied STAR concepts for Windows 1.0, but for Windows 2.0 they copied ideas from Apple without payment or permission (and if you think Windows = Finder then you're an idiot). As I said previously, it was those parts that Microsoft lifted (like redrawing uncovered sections of a window) that caused Apple to sue them.
