Tornado Cash is a protocol which can be used by both good and bad actors. Saying TC was responsible for bad actors laundering their crypto through the protocol is like saying auto makers are responsible for car crashes or Bob Kahn is responsible for all the illegal activities on the internet.

It doesn't have to be used for money laundering, and even if using it to move funds anonymously, that doesn't mean you're money laundering. There are good reasons to not want individuals and state actors whose jurisdiction you're not under to track your financial movements, even if you are reporting your income accurately with your own government.
