What? It's nothing of the sort. Pubmed is not a preprint server. The paper in question was accepted by a journal. The quality may not have been great - I agree - but it is not like the archive at all.
He means it’s a resource for finding any/all articles, irrespective of source journal or quality - specifically pointing out that people shouldn’t infer anything from the NIH url.
Seems that way, I know, to some of my friends who don't work in the same field as me (health research), but pubmed doesn't include all biomedical journals, and it's not a place where anyone can archive papers independently. Which isn't to say that everything in pubmed is high quality or that it's a great gatekeeper, but yeah, it definitely excludes material.
