You don't need to put a single dollar into Brave's BAT in order to get paid in them when volunteering to get ads from their ad system (which companies pay for btw). You can easily sell them for hard cash. Your pyramid scheme example doesn't work here buddy.

The browser does a man-in-the-middle attack on webpages. It’s sketchy, dodgy and scammy. It was bad when they introduced it, but in 2022 it completely indefensible.

I don't think you understand what a man in the middle is or how it works at the browser engine level but sure keep repeating it.

Are you claiming that ad blocking is a MITM attack?

No. Brave browser hijacks webpages that you view and injects their own adverts onto the webpage.

The webpage you requested is not the webpage you are shown, because of the man-in-the-middle attack.

The ads are notifications. They aren’t injected into the page.

You clearly have never used Brave.
