I think this has a large effect on opinions in an often revisited internet topic "moving away from ads". Whenever a service starts to offer a paid alternative, or people get on the topic of tracking, or micropayments comes up, it's always struck me that commenters seem used to effectively free content and seem to just ignore that there are people subsidizing their internet usage by clicking on ads comparatively all the time.
I think it would be wise for us to reflect on, and admit, that we (power users) are currently getting a far better than average deal in providing for the web services we use.
Quality content, services, and products are expensive to make. An internet where we pay for it instead of it being supported by user targeted ads isn't going to be covered by paying 10 cents per article you really liked.
