You know, first time I encountered the "M$" shorthand was in a TELEX (look it up if you don't know what that is) from Commodore Corporate about pricing of the the PC10 computer. I have used it ever since, based in part on what was not very diplomatically expressed in that missive about M$'s attitude to licensing.
as long as I can use the term I coined: "open shit"
Actually, the proper traditional way to insult Open Source is "Open Sores". Use that and the feeling I got during flame wars between high schoolers on IRC channels in the late nineties will be complete.
A friend of mine is really big on the term "freetard" for open source software.

This kind of passive-aggressiveness only reinforces the grumpy-old-man stereotype and makes it really hard to take you seriously.
Just because you read it a long time ago doesn't make it less petty or silly.
