user I have reviewed the web page, and while it is true that he makes a deep analysis of the behavior of the software he tests, his personal considerations, in my opinion, make him say crazy things. For example, he indicates that Tor Browser and Librewolf have some probability of being spyware, but then he indicates things like that Brave has a high risk of being spyware, at the level of Firefox and Vivaldi. Also many of his articles are outdated, he ignores the privacy policies of the respective software, in many cases he only takes into account the basic features of the program, without configuring it or anything... I don't know, he doesn't seem very reliable to me. I can understand his articles, but the opinions and conclusions he draws seem to me either exaggerated, or directly ignorant. And to consider Waterfox less Spyware than Brave, I don't know, it seems ridiculous to me. But well, expression and information are free. I certainly don't have the absolute truth, and surely I also have some bias, so... Just draw your own conclusions in this regard. Best regards.
