If someone made a proxy, and wasnt in it for the money, Then id have respect for them as a person, Because he wants to make money off it, i respect him as a business man.
Shame he wont update CID proxy though, that came in useful a hell of alot of times. But you have to ask yourself, if you was in the situation, where thousands of people would pay to use your work, or you could keep it free, What would you choose?
