This shows you don't know what you're talking about. Brave's results are very similar to microsoft bing's. Because those who first made Tailcat designed it in such a way. Many have also remarked upon its similarities. But any excuse to keep using google and microsoft I guess. You can call it convenience, but it keeps them in control.

Btw, metager may use other sources, but none compare to bing's inclusion. It delivers the most results in that list, because it's the biggest.
