I've managed to escape most such things, but, uh, it annoys me when people think they get to tell me what to do, without paying me.
I've spent much of my free time as an adult on free software development, but that's because it's fun. It's volunteer work. It's a gift. If someone wants the right to tell me what to do, I'm happy to discuss hourly rates. Fair warning: I value the freedom to do what I want in my free time, and thus the price will be quite high.
