"I don't think you can crowdfund the development of a game without being
about halfway done, anyway."
Well, unless you have a very big name and a strong fan base, i actually
agree.
I think you really have a point when it comes to video games.
However, it was always comparatively easy to make money out of free software
video games, since developers could just keep the non-functional data
non-free, and yet the sector is so heavily dominated by proprietary games.
So maybe it's not that they don't have an option to make money out of libre
games...they just don't want to because people buy non-free games anyway?
Maybe it's like that...
