Microsoft during the late 80s and 90s was famous for its ruthlessness and the way it exploited and crushed its competition. I wouldn't say "Jobs is the nasty one and Gates is the nice one"
Jobs was exactly the same way, he just happened to lose the PC battle. Bill Gates famously tried to help him license the the Mac OS to other PC manufacturers (displacing DOS!) but Jobs thought he could beat them all across the entire stack.
