primrose You say "If you know the company accounts are wrong, report the company!"
I, and most other people, wouldn't know that a company's accounts are wrong - how could we? That is up to their accountants or a "whistleblower" in the firm. The watchdog itself is saying that some very large accounting firms are not carrying out thorough audits. Some people might wonder whether, if they are too meticulous, their clients might decide to go elsewhere.
You say: "So what if accountancy firms are rubbish, corrupt, unethical ........" Really?
You go on to justify that statement by saying:
"The quality of Richard Murphy's work seems to be in line with most other accountants".
I don't see how you could possibly know the quality of his work. Accountants working for huge companies have a vested interest in keeping those companies happy. Richard Murphy does not.
