My holy grail of FOSS is a version of creation kit where modders could create their own Elder Scrolls like games.

I used to think so. It’s ideologically sound except for allowing corporations the same free use as anyone else. There are plenty of forward thinking people who would never want to support the oppressive evil of massive technology corporations and would never intentionally help them. Then they publish free software and directly help them anyway. It’s not a coincidence that most “free” software is funded by the US tech industry who is directly benefited from it. I’m not sure of a way to change it that would help regular people faster than it helps private industry crush regular people.
