This guy is incredible, I've been following him on Twitter since his Ueno days. An amazing designer and leader. One of my favorite projects he worked on was to literally build ramps all around Iceland: https://rampur.super.site/
Looks like people mostly praise him for those ramps, his bar, his awards, and how cool he is in general. It's still not clear what he got done at his job.

Not "they created a tool and it got misused" but instead "these specific criminally sanctioned folks are using our tool to launder 600 million dollars, and we know, should we do something about that?"
Their messages back up that they know it was being used in a specific instance, by criminals, to launder money, and they did nothing.
Sorry, no sympathy. I'm with you that we need to ensure tools are available, and i'm even okay arguing about KYC/etc.
But when you have specific, actual, knowledge that a criminal actor is using your tool to launder money, and you do nothing, sorry, that's just aiding and abetting.
