Adblock Plus which is the topic of this lawsuit is an ad-replacer rather than an ad-blocker -- and they make money from their own ads. I can see where that annoys publishers (and marvel that they manage to get any users).

From the article:

> While it offers ad blocking software, the company generates revenue from ads through its Acceptable Ads program – advertisers pay to have ads that are "respectful, nonintrusive and relevant" exempted from filtering. Non-commercial open source projects like uBlock Origin rely on community support.
