The intention is B, and it would indeed be a dick move if you could pull it off in this massively interconnected age. Remember when steam briefly pulled Hatred? There's no evidence that made it harder for anyone to obtain the game indeed, it might have just made it more attractive to the edgelords who bought it straight from the manufacturer-which might have had something to do with them backpedalling on their own internal ban.
I understand condemning the desire to make a game unavailable but if the means to do so that's employed is completely ineffectual, again, why should I care?
