So what? Even if it isn't some well-reasoned whitepaper, there's nothing wrong with venting a little. It's possible (desirable, even) to be sympathetic towards people who haven't written a thesis defending themselves. Often those are the people who deserve sympathy the most.

(I also disagree that the author doesn't give good arguments, sure it doesn't mention the exact word "lies" but a good chunk of the article is in the same embedding space cluster.)
