EDIT: oh I think I initially misunderstood you. You mean you don't see a connection between Omarchy and the project, not that you didn't see why the commenter included it in their list. You probably know the following already anyway. If you don't, now you know!

Omarchy is created by a far/alt-right white nationalist guy who doesn't like London anymore because there are too many brown people and who praises Tommy Robinson. And transphobic, but that's not surprising given the previous sentence.

(Note that in his article he says "native Brits," when the statistics he links says "white Brits." So he doesn't consider people of colour born in Britain to be "native Brits,", but doesn't want to outright say it. I wonder why.)
