Similarly an exception like a lawyer being a good ceo does not prove a rule like lawyers are bad CEOs. It's nonsense. People who don't understand the proverb took it and misused it and then others took after them and here we are, I've been wondering about that proverb my entire life and I never understood how it makes any sense. Now I finally do, and I'm glad the other commenter clarified it
If you research this, as well as the customer as always right as you claim, you will find no evidence of their longer ‘original’ forms [1].

There’s some quibbling to be had about the meaning, but it puts it closer to “assume good faith” or something like that, rather than reducing it to just preferences.
> The earliest known printed mention of the phrase is a September 1905 article in the Boston Globe about Field, which describes him as "broadly speaking" adhering to the theory that "the customer is always right".
> However, John William Tebbel was of the opinion that Field never himself actually said such a thing, because he was "no master of idiom". Tebbel rather believed it probable that what Field would have actually said was "Assume the customer is right until it is plain beyond all question that he is not."
The exception of a lawyer being a good CEO does not, in any way, prove that lawyers are not good CEOs .
The examples of legal signs and so on are a more specific, technical, meaning that is only used in certain contexts, such as actual legal proceedings or at least informal discussions about laws or contract terms.
When /u/flkiwi above said this phrase, they obviously meant it in the joking sense I gave, and which they had actually explained above. They agree that, in general, lawyers make bad CEOs, but they also personally know of exceptions. This is not "wrong usage", as proven by the fact that everyone who read the comment understood exactly what they meant.
This whole thing reminds me of the people who complain about the use of literally as an amplifier instead of for its primary meaning as "wrong", with seemingly no understanding of how flourishes and rhetoric work (nor even of the history of words like "very", which used to be quite similar to "literally" a long time ago).
The idea that there was some point in history were the pointer target was officially designated to be x is just false. That point in time never existed.
[All] lawyers are bad CEOs is a statement that was made. Evidence to the contrary was presented. "The exception proves the rule" was used to dismiss that evidence.
It's used in a similar way as "God works in mysterious ways".
