There are only two business models on the web: either you pay for your browser, or someone else does. This is why Orion is entirely user-funded, and can continue serving users by prioritizing privacy, control, and features like powerful, built-in ad-blocking. Not third party deals, ads, or any other incentive to corrupt the user experience and overall quality.

There are only two business models on the web: either you pay for your content, or someone else does. And that someone is usually advertisers. Blocking ads while consuming content upsets that business model. That's why Brave Browser's BAT is a fundamentally good idea marred by terrible execution. On the other hand I do not believe built-in ad-blocking in the browser can ever become mainstream for that same reason.
