You are likely correct but I just don't care about people making money from their websites with ads, and I imagine a lot of other people feel the same. The web was just fine before ads and it would readjust if they were gone.

When I see an ad it immediately devalues the brand being advertised, as well as the content.

In the end, people are free to have ads on their sites, and I am free to block them, and if enough people agree with me the websites dependent on ads will eventually cease to exist.
