It's a bit like when they want to know if you've family/responsabilities, I doubt it is to pay you a salary going with those, but more to gauge if you'll be a good slave or not...
Anyways, if I was in your position, I would do whatever I want, but without working for a company anyways, is not fuck you money (or attitude) at leaat, if you still have to obey the boss on all the bullshit right?
Best of luck!
PS: Oh now I saw your username, I've read you a lot arund here Chris, I think you're doing great with your own libraries/iOS stuff, I don't see why you might need to apply to a company, maybe you should start yours instead. You would make a good leader
