Well, there’s a good chance that most people who present technical information publicly are probably involved somewhere in the tech space. Pretty sure the owner of that site also has a disclaimer stating that he in fact works for Brave.
More directly, is the information on that website inaccurate? Could any other person create a similar website with the same information? Has anyone?
True facts don’t change based on who presents them. Every time I see this “oh don’t trust the Brave employee” it’s usually someone who is mad that FF isn’t the best in whatever category.
At least the Brave guy’s site included many popular browsers and not just the big 5.
