I think it's better to say that in science, many of the primary sources are closed. There's been a huge boom in open access publishing in the last 10ish years, so now well over half the journals I read are open access, and PNAS has an open access option. Especially when one of the egregious distortions mentioned was from PLoS One, there's just no excuse not to go back, glance at the article, and maybe any linked News and Views type articles.
