The way loosely-defined "we" call(ed) things in different periods of time isn't a good basis for conclusions, especially in topics in which there was basically no good science 50 years ago.
We agree it’s not a constant “we.” And also a lot of the current usage is secondary to pandemic politics where certain demographics and career slots benefitted or alternatively were hurt by covid related policies. My conclusion is only that language and culture change and influence one another.
