Well sure, the strategy of "tell people what words should mean" will work for some people like yourself, but clearly has not been enough to have the common use of the words switch over. I don't really know what the solution is, but there seems to be a very hard line in RMS's mind as to what the domain of "hacking" can be. He's extremely clever, a hacker, and a genius in certain areas (the GPL is such an amazing hack) but at the same time keeps banging his head against the wall using failed strategies instead of trying to hack his way to a solution. When was the last time you heard about something RMS did in the way he presented his ideas to be more receptive to others and thought "hey, that is pretty clever and a nice hack." I certainly can't think of anything, but he's clearly capable of doing it.
I think he probably has some personal moral code that prohibits him from trying to hack systems above a certain level of abstraction. Computers and security policies are below it, people's minds, emotions, and opinions are out of reach. In other words, the art of marketing is completely outside it.
YC on the other hand has a much higher bar for what is hackable, including things like getting user growth through clever marketing and viral loops, and keeping your startup solvent by selling breakfast cereal. RMS wouldn't go near these types of things, but they are in line with the hacking ethos.
