Is that what you base him being "controversial" on? My understanding is that he regularly publishes in the Lancet [1] and New England Journal of Medecine [2] (if I am using pubmed correctly).
His tone is controversial: he’s happy to say things that will make some people unhappy.
You are quoting a highly respected peer-review journal. Those were set-up to avoid appeals to individual authority and replace them with (anonymous) peer review. His presentation is certainly promising but it hasn’t gone through such a review yet.
