Anecdote about a magical disappearing operating system? And it is somehow the fault of the OS and not the MUCH more likely culprits, user error and hardware failure? Conflating UNIX and Linux as if they are the same thing? Your story sounds like naive exaggeration based on ignorance and hyperbole.

But you’re right, there are plenty of reasons to hate Microsoft that have nothing to do with open vs. closed source philosophies. However, saying that the foundational principles of open source software development are more sound than closed source development in general and the particular way Microsoft has chosen to develop is not the same at all as your “perfect system” straw-man argument.

By the way, UNIX was created in 1969, Windows was initially released in 1983 (but didn’t really take off with Win3.1 in 1992), and Linux began in 1991. So your final statement while technically true, I suppose, is kind of absurd.
