Firstly, bravo for not getting caught up in the oftentimes self-destructive world of social media, with its long list of promises (it'll make you more connected, happier etc.) and its long list of actual results (higher stress levels, lower self-esteem, less time for meaningful relationships due to more time spent courting superficial ones, etc.) The usual YMMV disclaimer: some people use social media more effectively than others, blah blah.
Secondly, always keep in mind that a good deal of human preferences and behaviour come from self-enhancement bias; in particular, we dislike everything that claims, directly or indirectly, that we're lesser. So if you're suggesting to recruiters that you're somehow better than them, that's not good.
Thirdly, always keep in mind that recruiters want a team player. If you're able to get a rapport going with others, that's attractive. If you're some weirdo with a superiority complex, that's unattractive. But if you're a likeable weirdo who comes off as a team player, that's probably okay, and in some contexts it will even work a little bit in your favour.
Fourth, the ideals reflected by Stallman are supposed to make not using Facebook a common and acceptable thing, by specifying that you don't use it, you make its use the default.
My specific advice is to leave this off your CV (because you don't want to come off as weird) and if you're asked about it, have an easy-to-relate-to thing to say about it. "Well, I used Facebook for awhile. It was great for organising events. Made it very easy to get the boys over for a BBQ. The chat was also a very good feature. But like many people, I was really turned off by the superficiality of it all. I guess in the end I just found better tools for connecting with others; Skype, even the humble email. Honestly, nothing beats a good face-to-face."
