She's a professional YouTuber (among other work), those sites basically require you to do that sort of thing to get and maintain traction over the long term.
This one isn't particularily bad and the content is fine.
That’s a bit unfair toward her. She’s not just a professional YouTuber. She is also a bonafide[1] physicist, who has spent years acting as a contrarian to the mainstream ideas.
Yeah but calling her a “professional YouTuber (among other work)” is a very blatant misrepresentation of who she actually is, considering the opinion most people, especially on this site, would have of a YouTuber. An HNer who does not know of her would almost certainly come away with the idea that much like most YTers, she doesn’t know much of what she is talking about.
When in reality, she’s a bona-fide professional physicist, whose knowledge of physics is why she’s a YT personality. Before she was a YTer she had (and possibly still does) have one of the better physics blogs on the internet as well.
