Ironically, that makes you the kind of person that the advertising company is the least interested in. You're not interested in buying what they're selling, you just want to cost them money. That means your "ethical" stance isn't really sustainable in the long term.

Over time, as advertisers realize they no longer getting any ROI, the funding will dry up.
