It's a classic example of the laziness of the bureau, taking down the entire exchange instead of chasing down the people that have allegedly committed crimes against the US. It is not illegal to run a crypto exchange or trade on one.
It's not laziness, it's tactic. The feds has gone from a few million to several hundred million in extra funding by using the civil forfiture laws. By immediately seizing anything connected to anything remotely suspected of crimes (which they can to since that law was passed), they get many many millions more of funding in a legal way by taking it from whoever happens to be caught in the crossfire. It's really hard to fight this as well, from what I have read. It's the way they work nowdays - instead of putting in the man hours needed to sort out the bad guys from the good, they label the entire exchange as a criminal cesspool and take everything they can get. Extremely provocative behaviour
