The OP responded. Basically, linux needs feminist spaces because FOSS communities are traditionally sexist spaces where their contributions are not welcome. The point isn't that no one else could have had the idea, that's absurd. The point is that no one had until that point, so it wasn't trivial. It's the banal idea that if we have spaces where marginalized groups are able to contribute without all of the extra baggage associated with being a part of the group. In the FOSS community, you face extra criticism as a woman.
