As a counterpoint to this I use Brave on my iPhone, Windows home PC and Mac work laptop. It blocks all ads, I don’t use the crypto at all and never have, and it works for 99% of the sites I visit including ones for various services around work. I never opted in or out of anything, it just works and because it blocks so much nonsense it’s fast. Frustrated by all that negativity when it works great for me as a “download and forget” drop in replacement for Chrome without all the Google tracking.
