Impulse Software Ltd owns the actual source code/engine that RsBots, AutoFighter, and a ton of other sites use. The reason why it's a big case is because multiple bot platforms actually use the software created by Eric and Mark Snellman. The brothers allowed other 'companies' to distrobute and allowed them to create their own bots using their source/software.
I would say that this was the biggest shutdown since RSBuddy's collapse. Bots like Powerbot will never be functional again because they run off a reflection based source. (Jagex recently rendered all reflection based bots useless).
As a Software Engineer and Developer, I will say this; there will never be a time where RS is bot free. Programmers will always find a way to create new hooks and ways to obscure Jagex's security. However, Jagex has a big advantage and can potentially win the battle if they press hard against developers with cease and desists.
