I use Brave as a secondary browser mostly for government websites because sometimes my firefox privacy settings breaks them and since many of them are poorly designed a technical issue over your account may result in hours on the phone to resolve.
Because it works, has okay configurations out of the box, and I just don't really care enough about the points mentioned in this article to make the switch. I only use it for cases where I don't expect privacy like government websites. As soon as you open an account there they got all your info anyway.
