Politics is not just the relationship between two people, it’s the relationship between a person and everyone/everything else in the world.

Reducto ad absurdum: would you suggest a world where every country is at war with everyone else would foster a better environment for global FOSS collaboration than one where the world was at complete peace?

I honestly thought the statement you quoted was entirely uncontroversial. “Healthy” and “global” being the key words, I’m not saying it’s a requirement for FOSS to exist in general or anything.
