With the current online advertising model, ad blocking will force publishers to take drastic measures that we as users do not want. We can shut down the ads, but the content will still have to be funded. We as users will still have to pay to view that content. Only in the future, instead of paying passively (by viewing ads), we will pay actively, being forced to deal with things like paywalls, freemium models, and subscriptions.
