The truth is I think Google's adsense business has never had any real true value to customers (except for perhaps their 'first page at the top' paid ads, I use them a lot, mostly because I figure companies willing to pay for ads usually are a likely 'proper solid business').
Most of the adsense these days is 'trick next buttons', where people put them at the bottom of a page that appears to be the 'next page' button, and it's not.
I spend absolute craptonnes of money of stuff I don't need. Internet advertisements I am exposed to contribute almost zero impact to my purchasing habits.
Except for Belroy wallets. I have no idea how they figured to target me ('hipster' programmer?), but I did end up buying a wallet from them when their ads followed me around for a while. And their products are nice :) But that is it!
I couldn't care less if they are giving backdoors to the NSA to all my email including all company crap that is confidential and all. If they put ads into my email I will look elsewhere unless there is a paid option.
