The whole fight about adblocking won't be solved in the court, but with a technical arms race. In the end startups like this one will probably win, just because there is a real, monetary gain for them. And then visitors of the sites using technology like this will have to choose: Either don't see ads, but also no (or not as much) content or content, but with ads or a payment. In my opinion this will lead to a better "contract" between users and the site, where everyones cards are on the table.
