Naive is a form of uninformed, maybe, but carries a totally different expression. Willful to the point of negligent is totally different than not knowing about a subject. I guess there is an argument to be made that PA authors are negligent, but I see it different in that there are as many PA authors as there are other authors that began with no or little knowledge of the publishing world. The difference is that PA exploits them. IF Random House chose to exploit them, many others would also be in PA authors' position.
As for the other, all writers yearn to see their work in print. Yearn. Desperate. Another point of disagreement, I suppose. But I could argue that PA authors yearn instead of being desperate.
We can disagree on these points.
