Actually, the point of this article is that it is something new... for the last few decades the medical establishment and of course the sun-screen industry have been absurdly dogmatic and absolutists, telling people to avoid all sun, and anyone who dared to say that it was OK or even desirable to get a bit of sun was vilified (in one case lost his position as department chair of dermatology at Boston U). I think this article is spot on. And like you say it doesn't say to avoid sunscreen altogether... it says: "Each person’s needs vary so much with season, latitude, skin color, personal history, philosophy, and so much else that it’s impossible to provide a one-size-fits-all recommendation."
