Don't they also run the default centralized coordinator thing and receive a commission from the mixing transactions?
There is not "they". Wasabi is not developed by a company anymore and everybody can run a coordinator, in fact the coordination service is currently provided by independent volunteers (you can become one).
There is also the cooperation with blockchain analysis (anti-privacy) companies which I'm sure generates the Wasabi team a good additional revenue...
Hahahaha I believed that nobody with an average IQ could ever believe it but it seems I was wrong. This was just another of the Samourai's masterlies targeting idiots.
