I think the same thing when I meet coders who spend their time on ways to get consumers to click on more ads. Or ways to track consumers. Or ways to trick consumers into providing their personal information.
As someone who works in the ad industry - by far the best way to get people to click on ads is to have better ads that are more relevant and interesting and correct for that person (and which tracking plays a supporting role).
In this case, they serve as a very efficient market to connect people with the goods and services they want/need which only helps the greater economy and benefits everyone.
