I can attest that’s companies, especially large ones will generally know the rules better than the various government agencies and people, precisely because they have an incentive to know, they pay people to know, and there is risk involved. They also usually make a determination that the reward is not only greater than the risk, but greater than the consequences, and they have always been proved correct in that calculation. That especially applies to the executives, the people who immensely profit and effectively never face any, let alone effective consequences, so peoples round them also just keep their heads down and look away or even just facilitate the illegal behaviors in order to brown nose and climb the corporate ladder.
It is somewhat astonishing, but it seems people are baffled when things don’t change even though consequences for corporations and executives are net positive. Why should they care when the c-suite runs off with way more money than before in the end anyways?
Take for example the recent greystar lawsuit by the government for essentially price fixing apartment rents, ie fraud, across the nation. Long story short; estimates are they profited about $2.2 billion every year, the government fined them/agreed to a measly settlement paid to the government; with zero relief or compensation to those they committed their crimes against, nor will the executives that made the illegal decisions suffer any consequences, nor will there be punitive consequences that make executives sit up in attention.
