This is a completely legit complaint if this screenshot was instead a picture of a bookshelf on some bookstore or library.
But medium is an open plataform which makes this complaint a little silly. Literally anyone can write about anything here.
Now, if you're just talking about all this not-so-successful people writing on how-to-be-successful, yes I do agree it is boring. But people want to read that kind of stuff, I guess ?
