It looks like the author's 2 main points aren't good reasons to "stop using brave browser".
Whether you agree or disagree with the founder's personal political views has no bearing on the actual browser itself in terms of privacy or performance, both in which it excels.
The other point about ads & crypto is also moot since those features are, by design, private, and can be very easily disabled. I'll concede that it's still bloaty in the sense that you can't fully delete them, only disable; this takes disk space but I don't imagine very much.
