It would be $30 millions for all sites combined, only a small fraction of that for each site. And every site would have to invest some money to integrate with such an offering. And you probably need quite a few site to make this work, nobody will pay much if it only gets you access to a hand full of sites. And this number hinges on the assumption of 1 % of the ad blocker user willing to pay which might be wildly optimistic. If it turns out to be only 0.1 %, you are down to $3 million for all sites combined. And there is of course the huge problem of bootstrapping this. Nobody will pay if you have no content to offer, nobody will invest into a solution without customers willing to pay.
