I have seen many people in this community either talking about switching to Brave, or people who are actively using Brave. I would like to remind people that Brave browser (and by extension their search engine) is not privacy-centric whatsoever.
Brave was already ousted as spyware in the past and the company has made many decisions that are questionable at best. For example, Brave made a cryptocurrency which they then added to a rewards program that is built into the browser to encourage you to enable ads that are controlled by Brave.
After creating this cryptocurrency and rewards program, they started inserting affiliate codes into URL's. Prior to this they had faked fundraising for popular social media creators.
Do these decisions seem like ones a company that cares about their users (and by extension their privacy) would make? I'd say the answer is a very clear no.
One last thing, Brave illegally promoted an eToro affiliate program making a fortune from its users who will likely lose their money.
I tried them a few years ago before I knew more about things like this, their CEO, etc. I had a problem with them continuously taking over my home page on desktop with their own homepage (much the way Firefox on android does now) after every update. I contacted them on social media where they went on a two day stent of making fun of me for having a problem and gaslighting me that there was a problem because zero other people had ever complained. Super professional there.
