What an interesting question. I am also not a lawyer.

Copyright has to be quite specifically linked to your work otherwise it's much more like a patent: you can't build X because I did. With copyright you can't build X but you can build Y and Z and they can replicate everything X does (that isn't encumbered with patents). In the case of games we have seen famous examples like Zynga being relentlessly-copied by Vostu, or Rocket Internet investing in "X but for Europe" where they clone entire companies. So there's some good examples of how copyright itself isn't even necessarily a defensible product when the output is quite close (almost identical with Vostu). It's hard to believe open source is actually more defensible!
