Tom Scott is one of the great YouTubers. I don't know him personally but he does come across as a genuine down to earth guy who just wants to share knowledge with the world.
I also only recently learned that he has a newsletter. He mentions it briefly in some of his videos but I have never seen him ask people to sign up. The only reason I found out about it is because he included one of my articles in it[1]. Definitely highly recommend checking it out[2].
