"Heritage is duty" refers to the heritage of computing, not of human beings. Completely non-outrageous in context.
"Command is service", ok, that explains why Omarchy isn't a democracy. I think many other FOSS projects aren't either, so I don't see anything outrageous in that either.
And you may of course disagree with their opinion on "Code-of-Conduct struggle sessions and identity-overload nonsense" (not words I would have used). Many completely well-meaning people hold different opinions on those topics.
