Thinking of how the Brave browser blocks ads but then replaces them with their own to generate revenue.
What if there was a browser/chrome/Firefox add-on that you paid ($2 a month?) That installed a cookie on your device that would then remove adds from all.the sites you visited, that gained a share of what you paid in order to remove ads for you.
So mass media sites, tech sites, etc. Would recognize your cookie, see that you've paid, and track how many sites you visited and then bill the company for how many users subscribed to the ad free service.
