I'm not owed free content. What I am owed is the right to determine for myself what code runs on my computer. Ads are visually oppressive, violate privacy, and are frequently vectors for malware. I am in no way obligated to allow any website to run them on my computer.

When a website wants to make viewing their ads mandatory for viewing their content, that is their prerogative. Most don't, and I'm not obligated to volunteer my CPU for their ads.
