The author is generally in favour of free content and argues that it is good for both the consumer (as there is no hassle) and the content creator as there are other avenues for earning money.
I'm just as in favor of paid content as free. But I also think creators tend to see the free-paid and open-closed questions too black-or-white, and therefore err on the side of closing things too tightly or giving too much away. There are many, perhaps happier, middle ways.
