I have a single peeve with this otherwise excellent article: "My after-tax salary is less than $100,000 USD/year, so by definition it is impossible for me to exercise my options without borrowing money."
This fact isn't true "by definition". It's true "by arithmetic". We say a fact is true "by definition" if it isn't true for any other reason. [1]
