Never. I can't even imagine wanting to sell my freedom.
EDIT: I'm not sure why you would like it, either, given that the iOS games in your profile appear to be derivatives of more popular ones. If some legal department felt that you crossed the line somewhere in one of those games, you could have all your accounts suspended. That's not 10x the profit, that's 10x the risk.
I personally don't have any problem with your games, but you and I aren't the people who have to be satisfied. Your competitor's legal departments are.
There's plenty of precedent for overzealous legal departments sending out baseless legal threats already. Under SOPA, they get to shut you down right away, then leave you to clean up the resulting mess.
This is a classic case of the "prisoner's dilemma". By supporting the bill, you may increase your profit (but probably not by 10x). However, you interfere with legitimate businesses, and thus cause a net loss to society.
The threat is that some day, the other companies will support a law which is beneficial to them (and bad for you). Systemically, it is best for us to cooperate to achieve a group maximum
Those hypothetical money trees probably seem real to SOPA supporters. Among other things, this article explores how some wild guesses about hypothetical job losses from a 1986 speech keep getting cited as facts by Congress:
You make the fatal but tragically common mistake of assuming that if somebody thinks a program is worth $0.00, they would think it would also be worth $[however much it legally costs] if getting it for free was not an option.
I see what you're getting at, and I think that those piracy rates are at best accurate and at worst much higher. And as a game dev I would like to see more people paying for the software I work on.
However, there's absolutely no reason to suspect that SOPA will make a significant dent in piracy rates. On the contrary, as well as making little piracy impact, the industry will become increasingly constrained and there will be greater risk for developers.
