Linguists of English sometimes refer to using native (Germanic-derived) words instead of Latin-derived words as speaking a modified language called Plain English, even if there's more to speaking plainly than just that.
Using the long Latin-derived words lets you sound smart, needn't be a bad thing – akin to dressing well. It may also obfuscate that you don't know what you're doing, useful when you seek employment or publication. But when your highest desire is that someone understand and learn from what you are saying, speak Plain English. If scientists have a responsibility to reach out to society, speaking plainly is a high skill of science … and such language ought to be favoured in publications, when you think about it.

(<2022-Mar-17> I'm not sure if the quote is about Native over Latin, or just simple language.) Some precedent for mandating simple language, from lawyers of all people:
In legal writing, David Mellinkoff, a professor at the UCLA School of Law, is widely credited with singlehandedly launching the plain English movement in American law with the 1963 publication of The Language of the Law.[15][16] In 1977, New York became the first state to pass legislation requiring plain English in consumer contracts and leases.[17] In 1979, Richard Wydick published Plain English for Lawyers. Plain English writing style is now a legal duty for companies registering securities under the Securities Act of 1933, due to rules the Securities and Exchange Commission (SEC) adopted in 1998.[18] In 2011, PLAIN (Plain Language Action and Information Network) published Federal Plain Language Guidelines.[19]
If plain language is so important in legal writing, then in scientific writing… given that journalists and even many antiscientists (like anti-vaxxers) now read abstracts for themselves and it has an impact on society… we should be able to mandate it too. The plainer it is, the more people might get started doing science themselves.
Science started out as something only the most fortunate members of society wasted their time on, which is why the language du jour is still so opaque, as if to keep out the dregs. I opine that everyone can contribute something to our public knowledge pool. Not just those getting an university degree, but those in high school. That would be possible if the language got points for being the opposite of opaque and there was a review process not reliant on the honor system, then if a kid finds something genuinely new, or even just replicates a study, s/he can just write something up, have the teacher edit it, and submit it, adding to the public reproducible knowledge pool of humankind.
