Is Tornado Cash developer guilty of money laundering?

Is it fair to assume that the developer of Tornado Cash is guilty of money laundering simply because their technology has been used for such activities? On one hand, Tornado Cash is a decentralized and open-source protocol that enables privacy-preserving transactions on the blockchain. On the other hand, the technology has indeed been utilized by criminals to launder illicit funds. So, is the blame solely on the developer, or is it a complex issue involving multiple actors and motivations? Furthermore, should the technology itself be deemed illegal, or should the focus be on the individuals who misuse it?
