This is actually a good thing. Companies that can execute while rotating leadership are companies of rules, principles, etc, not companies of people. This is a very good thing.
So then it sounds like within this, part of what we think of as the prevailing morality can actually be defined as the behavior of companies who have been around for long enough. This is probably why a lot of companies seem to get away with "bad" behavior: people who think of the behavior as bad simply don't know the rules. Just be sure to throw in a token fine or fire a middle manager in order to preserve the illusion.
