I have to wonder if the cost isn't somehow related to the ginormous file size. I have to imagine that millions of people downloading a file this big constantly is expensive in terms of bandwidth. Maybe they want those downloading to truly have an interest in doing something with the toolkit and not just downloading it to look at/tinker with. A $4.99 hurdle is probably just enough to cull out a significant amount of downloads by people who probably wouldn't actually use it anyways.
