I was just trying to evoke some thought. If people are opting to flag spam, rather than opt out, then something is wrong. Sometimes there's a disconnect between what makes sense to us, and what makes sense to our market.
Something is wrong if you have to opt out of something you never asked for.
Just as those dreadful browser toolbars you get with a lot of installation packages (even java updates, how pathetic). If I have to actively uncheck that box you are an ass.
There should be a way to punish such behavior, marking mail as spam seems to have some effect.
