This is a bad analogy because it perpetuates a misconception of the basis of insider trading law (in the US).

Insider trading has nothing to do with having an information advantage. The markets and their regulators encourage those with an information advantage to use it to as full advantage as they can.

Insider trading is based on having an economic obligation to someone else. If you use your knowledge to make money and you don’t share that equitably with the people you have that obligation to, that’s insider trading (in the US).

You’d have to torture that definition for it to make sense in the job market and none of the examples in the article match.
