Tools are very hard to sell. Especially very specialized tools. And tools for programmers often come with the end-user price of 0, so justifying anything above that is hard. For me personally, I don't see the need to even use such a tool, let alone paying for it. Many programmers seem to focus on code, but in my experience, that's usually not the problem you have when things go bad.
