I am OP and, you are tight, I indeed feel that your answer is full of vitriol.

How, from a funny/nostalgic comment can you derive something like that?

In my world (France, mid-late 80's) IBM was known by everyone because computer = IBM. And computer = important, apparently.

Also the legend of 2001 Space Odyssey's "HAL = IBM shifted by one" was very much live.
