How does one actually piss off a programmer?

(Say, at a dinner party or in polite family reunion. Assume you're a cocky marry-in.)

Well, you ask that person to recant their GPL licenses. You ask all of them to do this. You ask them to take the document their hero, Stallman, the guy they don't talk about much, the document he drafted. Which they accepted into their hearts. And well, now they just don't talk about him much anymore.

You ask them to dig that guy up. And delete him from their repositories.
