I open source software when I feel it will benefit the greater community. But I've never felt pressure from the community to make any of my production code free. As a matter of fact, I think any pressure on developers to push their software free is silly - it should be a sincere offerring. Only sincere open source projects survive - otherwise you get the likes of half-assed licenses and crappy (but open, which isn't better IMHO) software. Keep what you want to yourself, as a developer, there isn't anything wrong with that and open what you feel like opening up - that's your right as a creative individual and professional.
