I don't think it is quibbling. It is a really important distinction. Salary is (mostly) guaranteed. Equity isn't guaranteed at all.
While equity in a public company can go down and go down significantly it’s liquid. Especially in companies like coinbase that don’t have a 1 year cliff, are public, it’s a significant part of your comp and not funny money like you get in many early stage companies.
Truth
The salary I banked at the beginning of the month is guaranteed.
Especially not at coinbase, whose stock has imploded to the tune of -75% just this year, and more since IPO.
