Watch the TV movie from the late 90s "Pirates of Silicon Valley" which pretty much paints both Bill Gates and Steve Jobs as really shitty people. I mean just look at what Gates did with the Altair. Said he had an operating system, didn't have an operating system, and what have you.
Then there's the whole Xerox Park thing where neither Apple nor Microsoft would be where they're at today without the engineers at Xerox who were pretty much forced to hand over their stuff because Xerox execs didn't see value in a GUI and Mouse. Gates and Jobs both were more than happy to go in there and pillage what was developed in order to create Windows and The Macintosh/MacOS
