If you don't feel you got value for what you paid, I'd suggest getting in contact with the developer to discuss your dissatisfaction with him. The idea of uploading code to be freely available just because you don't think it's worth what you paid is disgraceful. All you're doing is harming development. I hope you will feel ashamed and rethink your actions

Personally I haven't ordered the beta as it's not that important to me right now. If it was, I wouldnt mind donating. If you are serious about pen testing I don't think $40 is excessive, especially if the problem of the injection driver is solved. From what we understand it cost the developer a lot to jump that hurdle, whatever your idea of "open source" is. I think if you don't understand that and don't want to help with these costs then you shouldn't really be ordering this beta at all in the first place.

Which begs the question for those with the beta, how well does the injection driver work? is it the real deal?
