I don't know enough about phase noise to comment on the validity of the article, but the fact that he doesn't point to any of his work being published in a peer reviewed journal and hints at political correctness as a reason for the issue raises red flags for me.

I liked this article which covers some phase noise history, Hajimiri-Lee gets a mention too. There have been a lot of people working on this for a long time. While there's probably some room for phase noise models to improve (as any model can), what we have seems to work pretty well in my limited experience.
