The SEC quote is about requiring auditors to meet their professional standards. Those standards require them to follow certain processes, things like needing to see evidence for certain things, and not both preparing the books and auditing them, and require that they not issue letters they don't actually agree with. Those standards do not require informing the public or regulators about problems they find.
There's certainly something to be said for having some codified professional standards for infosec professionals, but if public or regulator notice is something you think is important to be in those standards you shouldn't model them off of the standards for auditors, because auditors have no such professional responsibility.
Twitter is a publicly held company.
I'm sure there are conflicts of interest and some degree of confidentiality for auditors and clients, but there is a fundamental public interest of disclosure, at a minimum to the government, in the event of irregularities.
From the SEC:
"In addition, we will continue to focus on auditors. As the Supreme Court noted nearly 30 years ago in U.S. v. Arthur Young & Co., 465 U.S. 805 (1984), auditors play a crucial role in the financial reporting process by serving as the “public watchdog.” So, it is important that we carefully monitor their work and ensure that they fully comply with their professional obligations. If there is a significant restatement or if we learn about improper accounting from a whistleblower, our proactive efforts, or the media, then you can expect that we will scrutinize not only the CEO, CFO and Controller, but also the engagement partner, engagement quality reviewer, and the auditing firm as a whole. We are going to probe the quality of the audit and determine whether the auditors missed or ignored red flags, whether they have proper documentation, and whether they followed professional standards.
-------From there you can see legal and institutional gravitas, ethics, and expectations of accountants and auditors of public companies. That's kind of what I'm getting at re: elevating security and certain IT roles to higher responsibility and codification.
Now, is this a smear attempt by Jack Dorsey in relation to the Elon Musk lawsuit? Eh, maybe.
