You're probably right. The hurdles are high: "Ethical approval was granted by the National Research Ethics Service Committee, Southeast Scotland 02 (reference 12/SS/0201) for the study using the EAVE II platform. Approval for data linkage was granted by the Public Benefit and Privacy Panel for Health and Social Care (reference 1920-0279). Individual written patient consent was not required for this analysis."
"And that’s why only the good people, like the chosen 47, are going to gain access."
I do not share your optimism that all 47 authors are going to gain access.
