Sorry, but that is a really weird justification. It seems to me that is just the type of issue that corporate boards are designed to handle without the need for vigilanteism.
In this context it is a bit of a reach but I don't think they're wrong, and I don't think there's a reason to expect normal workers and CEOs to follow the same logic.
These kinds of comparisons, where two vaguely similar situations are considered equal regardless of the wealth, power, or influence of the participants remind me of this quote by Anatole France:
> The law, in its majestic equality, forbids rich and poor alike to sleep under bridges, to beg in the streets, and to steal their bread.
