Adding to that, if someone persists in calling me names for using a product they don't like, I can safely conclude that they are not my ally and that they do not have my best interests at heart.
As a satisfied Facebook user, I interpret RMS's rant as him personally declaring that I am his enemy. I have no desire to support him, his projects, or anything he has to say. In fact, I'm likely to oppose everything the FSF does on general principle.
I decided a long time ago that if I publish the code to any of my personal projects, I won't use any GPL libraries, and the code will be under the MIT or Apache2 licenses and not any GPL variant. After seeing RMS continue to go off the deep end, I'm specifically going to find a license that's subtly nonfree, and if not I'll make one.
