It may not have been. The author of Urbit is Moldbug, who is... controversial.

On the other hand, I just read the article, and none of it seems particularly bad faith. I vaguely remember something about Urbit using planets and galaxies as some kind of ownership metaphor, so I expected the article to go on at length about how strange this seems. But it seems to be focusing on the technical aspects of Urbit, and is pretty clinically detached.
