They block the in-page ads and instead provide their own ads through popup notifications.
So they are replacing advertisements on websites.
- The ad blocker works separately from their own ad service.
- Their own ads are opt-in.
- People receive 70% of the revenue from the ads they see.
- The ads from Brave do not track you and whatever personalisation happens in-device, no data is mined.
So, no. They are not "replacing" anything. They are not stealing anyone's revenue (and no matter how much Linus from LTT argues, he is not entitled to any revenue just because I watched any of his videos) and Brave's own ads are from deals that they closed themselves and a essentially fraud-proof compared with whatever payouts are given by largest ad networks.
In other words, they are just offering something that happens to be infinitely more user-focused than the status quo. Every attempt at framing this as unethical came from an uninformed or biased source.
