Yes, but they chose that route rather than for example expand their admin-team.
They would rather remain a small tight knit community than expand for fear of loosing their core values.
I’m disagree with their aproach but understand their reasoning. In the context of a instance war however I think they’d avoid conflict and thus remain impartial.
I mean, one of the central goals of communism to abolish ownership of the means of production.
Software used to produce something of value is a resource that in a communist society should not be owned. The only way to achieve this is to let everything be opensource.
So communists clearly like the free software movement, whether inverse is true is a matter for debate.
