It can be summarized as "Non cryptographic PRNGs can be predicted! Look, I cracked this one! I'm not going to tell you how I did it though."
There's no exposition describing non cryptographic PRNGs, nor any evidence given for why they're not sound beyond the author's assertion that he cracked one.
To be clear, non cryptographic PRNGs are often predictable, and shouldn't be used if that's a problem, but if you're interested in learning more about that, this article isn't going to help you much.
