I am sick of the brouhaha about goodmail.
Sure, it will cost. Sure it will be used at some point to do evil to someone, and sure that sucks. But the alternative is far suckier to the spam-o-philic max, and we are living with it now.

When you pay for something, you have a chance to control it. Spam is a market phenomena, NOT a technological phenomena. Paying for clean email makes sense to me because it lets me manage my inbox.
