> If a far-left activist made an overly non-political game incorporating the work of other leftists, they would catch flak from their own compatriots over betraying their principals for money.

I don't think that's true. It doesn't make any sense. Leftists would obviously be perfectly okay with collaborating with other leftists on whatever.

The point was that people on both the left and right should be okay with collaborating with people of the opposite end of the political spectrum when it comes to apolitical projects.

Imagine you were only allowed (or willing) to contribute to the Linux kernel if your personal unrelated political views align with those of Linus Torvalds. That would obviously be crazy.

> Look, "separating the art from the artist" is all very well, but we can't do that without acknowledging the political views of the artist(s)

Absolutely we can! We don't go around referencing the political opinions of our car mechanic or hair dresser, because these don't matter for the quality of their jobs. Exactly the same holds for game designers who make unpolitical games.
