Not just companies
"some companies just don't want to hear bad news – which makes it all the more important to get through to them"
Such examples are minor signs of a very deep problem. Eric Haseltine's 'The spy in Moscow Station' [Icon Books 2019] describes the extraordinary contortions that various US government agencies went through to ignore evidence that pretty much all official communications to and from the US embassy in Moscow were being read in real time by the Soviet security services. This got as extreme as, when hardware keystroke exfiltration modifications were found in a golfball typewriter used in the Ambassador's private office, it was rumoured that the NSA officer in charge of the discovery had fabricated the evidence to improve his career prospects.
