A healthy global FOSS culture requires collaborative politics to be the flavour of the day
Bullshit. There’s no reason people with political differences can’t collaborate on the same project, unless those differences are really huge.
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.
