The problem of open source is one of scarcity. People don't pay for value, if that value can be obtained for free and without effort. People pay for scarcity and our whole economic system is based on it. Open source unfortunately is the exact opposite. Note that there are open source projects making money. For example Wordpress is GPL, which forces all plugins and themes to be GPL-compatible as well. And there are plenty of commercial plugins and themes selling quite well, all of them open source. But that's not necessarily something Mozilla could emulate.
