I've seen that image circulating around a bunch lately, and not to totally kill the joke, but that's a 30 year-old paper they're trying to access. Many journals (particularly more "prestigious" journals such as
Nature and
Science) have switched over to fully or partially open-access formats (meaning that the paper is totally free for anyone with an internet connection to access) for current articles, though archives (particularly >10 years old) are often still paywalled even in those open-access journals. FWIW, even for most paywalled (scientific*) papers, if you write to the corresponding author, they can send you a copy of their paper for free, as long as you don't state an intention to use the paper commercially. Granted, I'm not sure quite what happens when the author has died (as in the case of the article above, where the author died in 2006).
Also, that article is indeed
available online for free should anyone care to read it. (And it's about how science is hard for laypeople to
understand, rather than actually being able to
access it to read it.)
Of course, outside of that one specific paper, open access isn't without its issues - primarily, that the cost of publication gets redirected onto the author(s). The last several papers that I have published have all had higher charges due to being open access, though we now budget for higher publication costs when writing grants. And an unintended consequence of open-access publication is that the increased fees for open-access publications may result in
fewer lead authors from underrepresented countries publishing OA articles (n.b. both that more "scholarly" article and
the more lay-friendly version are open access!)
*I am wholly unfamiliar with current publication access practices outside of the fields of science and medicine!
