This is idiotic because they blame him on the usage of the people who have used Tornado Cash. This has created a dangerous precedent on anonymous coins, tools and projects in the cryptospace. It also appears that the developer can be charged for the crimes that another person has done. Does this imply that if a terrorist used a Nokia cellphone to detonate bombs, Nokia is also implicit to the crime? A very headshaking argument.
The system is rigged. It's all hell-bent towards criminalizing crypto or anything that respects or encourages user financial privacy and freedom. It's stupid how they use the excuse of anonymous transactions getting used to "finance" terrorism yet the very hypocrites like the US openly finance terrorism under the guise of weapon aid to their allies using tax payers money.
Another lesson to learn is to completely go anonymous when creating tools that anonymize other users or enhance their privacy. It makes no sense if you are to develop a tool that enhances user privacy, yet you are out there in the open known by those Government blood suckers. They will dump all their shame and anger on that one person who created the tool once they land on him/her.
