To be honest, it is hard to refuse free things. But I prefer to work part time on simple non-prestigious jobs, to fill my needs, to be independent, and all other time work on future projects. This is not only question of pride, but this is absolutely other view on world. And I could only be responsible for my own behavior. For others, I know from experience, that large percent of people play fair, but not all, and need some measures against those people, who don't want to play fair. Who interested, google free-rider problem.
