Most people (think: GNU wizards) who do projects like this don't want to monetize; not for capability reasons, but for philosophical and social reasons. They think monetization is against some principal of free software, or their morals, or that people will stop using their software if they do, or, simply: they're lazy and just want to code, without worrying about menial things like income.

And then, when they can't afford to work on their project anymore, they want our pity. They don't have mine.
