It is important to emphasize that Tornado cash is not a company but a smart contract that no particular person controls
It can't be a smart contract no particular person controls, because someone just controlled it. Banning repository, the main site, the developers etc., would only make it harder to access their software, but if it had been used by thousands of users already, it could also be reused.
This is the same as banning JoinMarket from every clear net site. You've made it more difficult to do CoinJoins, but you haven't prevented its users (makers and takers) from re-sharing the source code, or even stopped their activity.
Are there other code hosting platforms besides Github that are not based in the US or upon which US Government sanctions have little to no influence?
