The author did write "better yet, let applicants do a take-home, and pay them for their time. ... think of it as another chance to be selling them on joining your team over some other team."
I added that after-the-fact in response to this comment. So that's on me for not including it originally. It's a great idea and one I wholeheartedly endorse because it forces the company to put some skin in the game and helps limit the number of applicants that they would request perform the take home test while also recognizing that applicants' time is in limited supply.
