Adults like gambling. It’s not Valve’s fault that children are using it cause their parents are ignorant of their own child.
If adults want to gamble, fine. Let's enforce gambling laws and get this over with. It would also solve the children gambling problem because that would be illegal. But this is why Valve's gambling service is indefensible. Valve is actively trying to prevent the gambling classification because if it gets treated like actual gambling it most likely stops being profitable. I don't necessarily have an issue with gambling, I have an issue with it not being treated as gambling. And all the other things Valve has done that have been positive for gaming do not justify giving Valve a free pass on gambling.
To bring it back to Gaben, he isn't avoiding taxes but he is avoiding the (gambling) law because it makes him more money, so is it that different from avoiding taxes?
