I cannot see what is so WILD about this aside from the author's preceonceived notions being subverted.

Is this deceptive/unethical if they are getting their job done? I don't believe so. Contrast that to /r/antiwork where many people there maintain multiple jobs to make ends meet - I would call it more unethical that such a situation is being normalized and accepted.

Or contrast that with CEOs who sit on and are paid by several company boards, such as the author of the tweet... who sits on other boards themselves.
