>(don't mention Brave, I'm gonna get mad) Just wonder the reason? Is it because it support the monopoly of google rendering engine? Or other reasons?
Not OP but I've avoided Brave from the beginning because of its reliance on an ad-fueled crypto scam to generate revenue. If you're trying to avoid Mozilla's new ad-based revenue scheme, moving to a browser that is wholly funded by tracking your browsing and showing you ads while pretending to "pay" you with cryptocurrency that they never actually pay out, seems like a step backwards.
Their ad setup works the same. The browser downloads an entire country-specific catalog in one go, and decides what to show you completely locally. Whether you trust their cryptographic setup that tells them you've seen an ad is another thing entirely and is its own brand of black magic.
But the basic setup is simple. They sell adspace and show you ads from that local catalog. Brave takes a cut, users get a cut. They have a tipping service to compensate creators.
There's definitely parts that might be suspect, like that proof of having seen an ad.
And even if it all works just as intended, there is the concern that ads that don't track are generally less valuable so even widespread adoption of Brave's system would cause a decrease in ad revenue and thus ability to keep sites up and running. We've already seen the fallout of Apple's recent anti-tracking changes, and Brave's system is definitely similar in effect.
