Auditors are hired by the company being audited, have a very narrow and fixed mission justified by previous financial blowups that caused a lot of concrete damage to specific people, and there are strict standards defining what they are looking for and how. Audits don't tend to suck up personal data of customers.
"Researchers" here means self-selecting academics going on arbitrary fishing expeditions with full access to everyone's data. It's not narrowly defined, not justified by prior unambiguous harm to anyone, and given the maxed out ideological bias in academia is clearly just setting up universities to be an ideological police force on the general public.
