Assuming the man isn't a hundred and two, the answer is clear - that old man has the right to curtail the profits of any business he wants by not buying their products. I'm big on some things that are addicting, too, and I buy them, but I don't pretend that it's all their fault becuase they exist. It was my choice to buy the product - I could have escaped. It boils down to personal responsibility. Like those fat people who think they have the right to sue McDonalds because it "made them fat". No, THEY made themselves fat. If they liked the food and McDonalds made a profit, good for them.
