If I allocated proportionally pieces of $5 to my favorite content producers a month they would get orders of magnitude more than what they get from me watching ads.

I hate ads, I hate the experience of having something in between me and what I want to do, having random images sent through my eyeballs, etc. So no, not everyone wins with advertising.

Google et al make more money (or at least think they do) through advertising and eschew micropayments for this reason, but that doesn't make micropayments unprofitable. And I don't want things for free if it means watching ads.
