GandhiCon
There is a quote from Mohandas Gandhi, describing the stages of establishment resistence to a winning strategy of nonviolent activism, that partisans of open source and especially Linux have embraced as almost an explanatory framework for the behaviors they observe while trying to get corporations and other large institutions to take new ways of doing things seriously:
First they ignore you. Then they laugh at you. Then they fight you. Then you win.
In hacker usage this quote has miscegenated with the U.S military's DefCon terminology describing 'defense conditions' or degrees of war alert. At GhandiCon One, you're being ignored. At GhandiCon Two, opponents are laughing at you and dismissing the idea that you could ever be a threat. At GhandiCon Three, they're fighting you on the merits and/or attempting to discredit you. At GhandiCon Four, you're winning and they are arguing to save face or stave off complete collapse of their position.
