The alternative to advertising is paid subscription content. I don’t see how you’re going to achieve greater privacy by giving someone your credit card number.
In the same way that the mp3 changed the music industry, bittorrent changed how Hollywood made movies adblockers are going to reshape how the internet works.
Because adblockers drive down the value of ads so substantially companies will give up on trying to pay their overhead costs by using advertising and instead switch to a Netflix like subscription model.
The irony with this is that once you’ve had to log in to a site with payment information your privacy and anonymity are completely erased and you’ve often given the provider the ability to run background and credit checks on yourself.
