If a scammer uses Kruw's coordinator and Wasabi to "clean" their stolen coins, that's ok and there is no problem there. Kruw and Wasabi aren't scammers for allowing that to happen. Everyone advertising Wasabi are heroes and privacy advocates.
If a scammer uses a mixer that later gets seized by the government, then the people paid to advertise said mixer are scammers and it's all their fault. They must also return all the coins the government seized.
It's a pretty messed up situation, actually. His reasoning is that any privacy service that takes custody is a scammer, because you could have used Wasabi instead. I do however remember him claiming that throwing a criminal in a dungeon and denying him access to privacy is justified. It's safe to assume that his opinions are highly influenced by what he's shilling.
It's needless to say that censorship resistant money should come with censorship resistant privacy, and therefore everyone should have access to it, despite ethics. I've noticed some of us arguing the opposite when it comes to stolen coins, which opens up the Pandora box to start censoring.
