Rational: Looking into digdeeper's section of the article and reading more into the issue, I've found a few problems:
1) Technically it doesn't whitelist anything, you can blacklist what wasn't blocked through other means.
2) Even if it did whitelist scripts, it isn't the brower that does that to my knowledge, but rather one of the browser extensions.
3) Because of this, you would just have to remove said extension to be able to start blocking what was once whitelisted.
4) It doesn't refuse to block _everything_ from twitter and facebook, just some of the scripts.
5) So that would mean that Brave's reponse was 100% in the right and linking to coveryourtracks doesn't make much sense.
If we were to bring this section back, it would have to be retitled "A slight limitation to one of Brave's extensions" with the above addressed.
