>>Just because you don't get paid, does not mean you have no vested interest in something. That's how something can be free and still be marketed. It's not a tough concept to grasp.

>no vested interest in something Hmm. are you talking about politicians - this is free, now free but behind of the curtain, where you don't see is something to mee too?

I have no idea what you mean. You can have a vested interest in anything. Your job, hobby, family, car, religion, philosophy, and yes, even free software.
