Oh-ho-ho, there's no way this is a new thing. I saw it all on the comp.os.ms-windows.advocacy Usenet newsgroup back 20 years ago, which, I have to say, was waaaay more entertaining from a trolololol perspective than anything a Channel9 poster could come up with today.
People at the time (but not a lot of them) were predicting that OS/2 and Mac OS would die out because of Windows 95 and NT. This of course was not at all obvious coming into 1995, given how much momentum IBM and Apple had, but it's actually what happened. Microsoft went on to outsmart OS/2 on the compatibility and user-friendliness front, and they became Apple's sugar daddy in order to keep their Office for Mac business alive and kicking. They won, just like the zealots predicted.
