I think that was part of it, and greentree lacked the skill to find a compromise, or the stones to give them a qualified (the audit is ok, except for...) opinion
Although in one of the cases, i forget which, they were trying to accept shares as payment for the audit, a huge conflict of interest that would pretty much eliminate any chance at the SEC accepting the audit as legit anyway.
generally speaking, if an auditor isn't going to be able to sign off on your financials they should know within one or two days when they do their audit plan and overview, and they usually will say "listen, we may not be able to give you an unqualified (clean) audit opinion" then let management take it from there. good management will say "ok, help us fix this", bad management will try to find a new auditor
but just reading a few old posts here, greentree has shown some bad signs that are the very things that have led to their poor reputation...giving out timelines (that's management's job), leaking details of the audit, etc
