On the contrary, this statement ---->  https://www.justice.gov/dag/media/1395781/dl?inline is good.

It means that they will not pursue privacy protocols like Tornado Cash, CoinJoin, and centralized mixing services, but they will pursue individuals who exploit these protocols to further criminal offenses such as terrorism, drug and human trafficking, organized crime, piracy, and the financing of cartels and gangs.

So they released the Tornado Cash developers, and it's safer to use CoinJoin wallets or advertise mixing services here. However, they will continue to pursue services that exploit/use those services for these dark activities (I believe this misconception is the reason they are pursuing eXch).
