Well, I can see their point. If the answer is readily available through standard sources, then they don't want to be bothered. The price is prohibitive enough that it will force most people who just want to be lazy (people who don't want to bother looking through references, or coming to a source like this forum) to try conventional sources. If the standard source doesn't answer, AND the question is important enough, then you'll pay the $25. It's brilliant, actually.
