I feel like you're jumping to conclusions prematurely. If you as health insurance specialist can connect these dots, you can be sure that researchers did, too. However, having a hunch is only the first step of a thorough scientific investigation, and those take time. Until we have collected and analyzed the evidence, this remains speculation, and scientists shouldn't go off spouting half-researched speculations. That leads to only more fake news. If you look through the Lancet or JAMA, you might find first articles on this connection (if there is one). But until there are peer reviewed papers about this, most researchers know that it's better not to speculate when talking to the press.
