It's opt-in, and the feature can even be completely hidden in the settings. Brave is an awesome browser. Certainly better than Chrome when it comes to privacy.
Is it a low bar? Chrome has the best JS and rendering engine in existence. Brave has all that, being a fork, and also the best privacy, except maybe the Duck browser. It's only missing the configurability and extensibility of Firefox, but that's arguably a privacy liability.
I believe the post was referencing the OP's statement that "Certainly better than Chrome when it comes to privacy.", not any kind of purely technical merits.
