If you walked into a cake shop and said, "Oh, I really love your confectionary, and I appreciate how long it's taken you to learn the craft, and your cakes would be perfect for my dinner party," would you expect to not pay for cakes?
Of course not.
Even if you then said, "But your cakes would reach appreciative mouths, and we'll want more free cakes every week!" you'd still be expected to pay for the cakes--especially when it's obvious that everyone else involved in staging the dinner party is picking up a nice salary.
Why, then, should a writer be expected to hand over a regular supply of "cakes" for free?
This lady's saying no.
