Yes, this applies to the original article -- and the minority use of this vernacular in general.
People (like myself, and I believe the original poster) take issue with the use of 'hustler' because we see clear parallels between the negative connotations of the term and those individuals that self-identity with it.
It's all semantics at the end of the day but I personally embrace the word hustler and would like to consider myself fairly ethical in life and business. If you're looking for that right person don't discount them because they call themselves a hustler, search for why they are who they say they are.
