I feel like I'm missing something. What the article claims they're doing is:
1. Misrepresenting what rights they have, and selling access to those rights.
2. Stealth-crawling the web, hiding from the webmasters just how much Brave is crawling their site, and making it impossible to block just their crawler.
How is either of these the right thing? I mean, for somebody besides Brave. What "attempt" are they making that other companies aren't?
The second doesn't seem like a problem to me as long as they respect robots.txt
But your original claim wasn't just "Brave are technically not doing anything illegal" or "they're no worse than the others". It was praising them for being better than the others, that they're the only ones trying to do the right thing. And for these example it's just not true, they're outright worse than the industry standard.
So, to repeat, what makes you think that "Brave is trying to do the right thing while other companies aren't even attempting"?
