That's worth knowing for some readers maybe, but for me personally after looking through the bullet points in that post, I found it didn't really apply to me.
None of the things he's criticizing were things I took away from the book. Examples, "If you're gonna go broke, go broke big"--> obviously stupid, just disregarded it; "Convinces people that college is for suckers" --> already was completing my degree, am well aware of the value of a higher education and also how it isn't for everyone, this had no impact on me whatsoever; "Advocates committing a felony: have rich friends for trading stock based on non-public inside information, he says "That's what friends are for." --> I am perfectly aware of what insider trading is and that it's a felony, again not exactly what I took away from this book.
And so on. What I took away was assets vs liabilities and using your money to make more money. That's it. And that's all I needed, that was the golden key.
