Penguin Pete outlines the symptoms of LIC (the Linux Insecurity Complex).
Describing one of the typical symptoms, Panic Attacks (thinking about how MS will sue Linux out of existence), Pete writes,
"You could drop nuclear bombs on every Linux user on the planet, but you'll miss at least one server housing the source code, to be found by some future archaeologist, and there it will go spreading again. Linux is creeping charlie. It is rooted too deeply to budge. Why do you think Microsoft is so afraid of it?"
So if you're a Linux user, you owe it to yourself to read his post and start showing some dignity! :)
