Neuromarketing only works if my rhetoric does. I'm just appealing to your logic here - I have no de-facto credibility and obviously don't intend to cast ads in a positive light. I'm not trying to convince you of anything, at least in the traditional sense.
Look at it this way, though: the last 15 years of computing have been characterized by the commodification of computers and the proliferation of advertisement. We're trapped in a stalemate because nothing beats free -- nothing. Ads subsidize marginal visitor fees, which account for the majority of online interaction. It makes a lot of sense for people providing online content, and hardware sales only further churns this content wheel.
So... steal your media. Install adblock. Keep backups and care about what you own digitally. Just don't pretend that you're funding a better world by buying the premium product - it's a bigger trick than advertisement itself.
