Earlier quoted context omitted.
Except of course that in the case of tether there has (AFAIK) never actually been a completed audit of their USD holdings. the closest there has ever been is a letter from a law firm that was related to the owners and which clearly stated that it was not an audit.
I think you're right. I saw a document that I thought was the audit report but it's a simple memorandum. https://tether.to/announcement-transparency-update/
They also parted ways with that firm because they were unwilling to provide what the auditor requested. They've never completed an audit, despite their website claiming "subject to frequent professional audits".
