I know it's a meme, but I can't resist saying that if you check his website out, you'll see he has all of his books and drafts available entirely for free and he also says he's agreed with the publisher to cap the book's price to something reasonable (which used to be true, I haven't checked now).
He's also nice in person, if you talk to him!
It's too bad that the meme is right and his legacy will be not having given solution to any problem ๐
Edit: fixed grammar
