"If you’re good at something, never do it for free.” - The Joker There's a difference between free and $0. A developer's goal may be to just build his portfolio, in which case giving away the software is more valuable than the cash he could make selling it. Nobody gives anything for free, the pricing just depends on the person's motivations. Another example is Google giving away Chrome because it wants user data more than it needs cash. I could go on, there are plenty of things more valuable than cash, depending on your situation.
