I'm not sure how creating illegal software has to do with determining and discovering new gameplay strategies, allowing people to become better at the game. Nor what it has to do with doing math and figuring out formulas for how damage in the game is being calculated. Both of these things are done without the use of third party tools, and contributes greatly to the game, especially to those willing to read up on said formulas and strategies. And quite a number of these come from BG.
