You mean like Earnst & Young who was just fined $100 million for overlooking cheating by their employees on the ETHICS portion of the CPA exam? I agree something is severely broken about Tether, but it’s also clear that auditing firms can be crooked, too. I would not trust an audit to expose Tethers shortcomings. After all, the auditors can only report on the documentation provided to them … they specifically do not determine the legitimacy or validity of the documents provided (iow, false documents are not vetted in any way).
Remember WireCard’s fraud? If not:
