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
And you don't seem to have read the article either, because clearly it was explained that they don't respect robots.txt because they have no user-agent.
