See the massive snowball that is open source software that has been rolling ang growing and will be taking over everything, given time? So far, it has taken over the internet, the embedded space and supercormputing. It's coming for your phone and finally the desktop. In time, you won't even be able to code and sell a proprietary game engine, because good enough or better ones will be available for free.

But for all this to happen will take years or decades yet.

Anyway, linux and open source and software freedom will be rolling along. That's just inevitable.

More interestingly it is also right and good ethically, while proprietaryness (in all its usefullness and shinyness) is wrong and bad.

Eventually FOSS will be usable and shiny across the board too.
