It isn't that simple. There are other issues that the developers may not want to deal with in using their own tech. Access to proxies is a big one. Obtaining lists of sites with enough traffic/page rank for this to matter is another. That said, these blackhat forums tend to be full of people with little money. Many users are from places like India and Pakistan, trying whatever they can to eke out an existence. Since almost none of the users on those forums have money to buy the tools (even $100 is a very high price point for products on these forums), writing tools for them is a fool's errand.
