A similar thing happened when the media learned about Ozempic (semaglutide) a while ago. Multiple progressive outlets, especially the Guardian, published articles stating the drug was overhyped, playing down its value, citing overweight women from "fat studies" academia (basically activists against the stigma of being overweight saying that being overweight itself is not the problem), emphasizing all its downsides etc. Of course they couldn't stop the hype, because the drug actually works.
Yet another example: In early 2020, for a few weeks many news sites claimed that face masks don't help against coronavirus transmission because there was "no evidence" that they did. Of course this wasn't true (the evidence was just limited, and the protection wasn't optimal), and they changed their tone quickly once multiple non-Asian countries started to introduce mask mandates for visiting public places.
See also effectiveness vs efficacy. If condoms are 100% effective but used incorrectly 20% of the time, they have 80% efficacy. It’s a useful stat when determining where to best allocate funds, but not for individual healthcare decisions.
