I have a book from Scientific American from the 1960s that has a whole section removed for the british audience because it contained instructions on how to run experiments on bears. That is a political act.
But, seeing as how administrations of various colours have differing approaches to funding science, its pretty hard for "science" to be a-political. Trump has expressed "policy" for completely removing NOAA, which provides massive datasets for wider research. His track record isn't great on funding wider science either. So its probably legitimate to lobby for more funding, no? (did the editor actually lobby effectively, is a different question)
Now, should the editor of SA also take on other causes, probably not. But "science" has been doing that for year (just look at psychology)
