In fact, it's probably safe to assume that anyone accepting investments from the Middle East or Asia has very likely dealt with or taken money from people engaging in the same or worse conduct, only that it hasn't been prosecuted there.
If this here is the standard by which things ought to be measured and decided now, then I would expect a lot of money be returned and/or given to NGOs and charities.
But then, I suspect this is mostly moral posturing and virtue signalling, so nothing substantial will happen.
