> In my experience the best information is always in websites with no ads. Like personal blogs, old pages, you name it. Seeing ads in a newspaper website? Why would I want to watch ads in exchange for being fed manipulating, half-true information?
To extend the metaphor: Malls often have common areas where you can sit and just hang out. They also often have cafes with tables. The common areas are often nicer than the cafes -- less loud and less cramped. If you like common areas better than cafes, by all means, sit in the common areas. But if you do sit in a cafe for some reason, you should buy something, even if it's just a bottle of water.
By a similar reasoning -- if you prefer websites with no ads, then by all means only go to websites with no ads. But if you do go to a website supported by ads, I think it's part of the implicit bargain that you be willing to view ads that are presented in a reasonable manner (where "tracking you across the internet" is not reasonable).
I don't like the concept of tipping -- I think people's salaries and/or bonuses should be determined by their managers, not random people who wander in. But if I go to a restaurant where tipping is expected, I tip, because that's the implicit agreement I made when I sat down.
