I suspect the disagreement stems from the idea that to remove advertising we have to find another way for people to pay for services which are currently ad-financed. It neglects other options such as those services getting banned and ceasing to exist because they're not economical. Or perhaps, if ads have any positive value at all, capturing that value in a less adversarial way and financing things we want through that. E.g. if we had an objective recommender service that made the economy more efficient we could tax it somehow and distribute those taxes to economically marginal but desirable services.
