If what they want is free, then money is worthless. It's a pretty simple barter arrangement. They share their own files so they get the files they need or want without having to use any money. If they don't use money, why would they want money? Get it yet? Money is worthless in some places in this world. This would be one of them. I have a reason to keep things legal, so instead of illegal versions of file sharing I use freeware, open source things like this OS I'm on. I legally traded skilled services for the hardware, and paid a tax on that as well. The entire computer hardware and software were free. The only money involved was mandated by the legal system, and they sure didn't motivate me in the least.
