The web browser Brave is marketed as a privacy-friendly ad-free alternative, but that's pretty disingenuous.
Brave exists not to protect privacy, but to make money from selling ads.
Brave is a commercial company funded by venture capital. Its business model is selling advertising and cryptocurrency investment.
One of Brave's owners is Peter Thiel's Founders Fund. Thiel is also the head of Palantir (https://en.wikipedia.org/wiki/Palantir_Technologies) and on the board of Facebook.
I do not recommend using Brave.
