It’s a fact of life that politics permeates everything, nothing is in isolation of the political climate it exists within.
The state of the world today is a function of the politics that got us here, a big change in world politics can have dramatic and far reaching effects.
A healthy global FOSS culture requires collaborative politics to be the flavour of the day—which is unfortunately not the case in a lot of countries currently.
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.
