The auditing arm of EY is in a completely different industry than McK and similar firms.
That EY's auditing track record is, well, checkered is a different problem. By throwing those two into the same bucket, so, shows some lack of understanding of auditing, accounting and consulting. EY also does, sometimes legally required "consulting" work for in the accounting space. That work is completely different from stragoc management consulting ala McK and BCG. And it also a different beast than the lower level outsourcing consulting ala Accenture.
