The biggest red flag here is that someone is trying to derive meaning from Eva, an anime whose religious/philosophical imagery and themes were used "just because they looked and sounded cool" (not a direct quote.) I mean I like it too, but it's gibberish.
I'll say this about OSS and the community around it: It's painfully obvious at times that while the individuals working on these projects (often thanklessly) are brilliant people, they often lack the communication and project leadership skills necessary to make a project thrive. The last few posts I've seen on this particular issue have been extremely vague and for whatever reason just won't come out and say what they mean. They're verbose, go off on tangents, and beat around the bush. We must first have explained to us the plots of TV shows, movies, and other ancillary things in order to understand what likely boils down to "people with differing viewpoints cannot find common ground." I see the linked blog post as nothing more than someone trying to work out relatively complex feelings about the time/effort they contributed to a project they no longer have faith in more than an "expose-eh." Given that people in the comments of previous threads have boiled the issue with NixOS down to a sentence or two, I think this is an accurate view.
