Try adding one of those papers to Mendeley. Or, for that matter, get it by request from the author. Legal and often fast. Add that. See what Mendeley does with the CiteRef.DOI and CiteRef.URI fields...
The reason this happens is Elsevier's business model. And this business model both really wrecked Mendeley and, I believe, contributes to medical misinformation being more dominant in the world.
And I don't think medical misinfo has much to do with Elsevier or academia. It's human nature, and the quality and degree of evidence-basedness of official communications doesn't really help.
Also, the words "misinformation" and "fact check" make my skin crawl.
If your conclusion is that the plebs is so dumb because they listen to Joe Rogan instead of The Science(TM), I think you're just digging in deeper.
Also, during the pandemic, many blue check Twitter accounts said it's a pity that so many conspiracy theorists and fake news believers are reading papers and playing around with data. They should just receive The Science, spoon-fed, and accept it, and too much thinking and reading hurts them. In other words, think about what you wish for. When other people are given access to data, they may reach different conclusions than the approved respectable media expert consensus.
Also, sci-hub exists.
