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.
An iPhone is a give-up on privacy because you don't get alternatives. If you don't like your stock OS on an Android phone you can just switch OS (for example GrapheneOS, CalyxOS, ect.). If you don't like the normal YouTube app you can just sideload a different one. You don't get this kind of freedom with an iPhone. A prime example of this is when, during the Hong Kong Riots where Apple pulled an app that assisted protesters.
