The problem with eXch is that it's a centralized service in an environment hostile to privacy, or at least to no-KYC exchange. If I were them, I'd simply comply with court orders (ignoring government requests), or at least restrict/review some transactions (flows above $50,000), or temporarily restrict the service when such events occur. While the above solutions aren't ideal, they're much better than losing eXch; we've lost a good service.
All that doesn't matter now after they have closed down their exchange, had some of their digital infrastructure seized, and lost millions from their personal holdings. That will probably have an affect on that supposed regrouping they were planning and having new owners take over and resume operations. No one from their team has released any official information since the seizure and we have no idea how their future will look and if there is a future at all.
