That's like saying Adi Shamir helps drug cartels, Tim Berners-Lee helps facilitate online fraud or that Henry Ford helped kill millions of people on the road.

All these people created tools that could be used by anyone. Encryption, the Internet, cars. All have legitimate uses cases just like Tornado Cash does.

To me, not wanting to have all of your public blockchain transactions linked to you is actually quite similar to wanting a phone detached from the hivemind - all you want is a bit of privacy.
