In this situation there is a co-author that wants their current funding source added to the acknowledgements section because they edited the paper that others wrote. The research in the paper is something the co-author worked on as a graduate student about 5 years ago, but they have since become an assistant professor elsewhere and no longer contribute to the paper's research.
The separate funding source they used several years ago to contribute to the data analysis for the paper is already listed in the acknowledgements.
The paper did not need major editing, but for the sake of scope - if the paper had needed major edits would that change the answer?
Never had this type of interaction before. I'm wondering if putting that acknowledgement would implicitly say that the co-author's current funding also funded the research in the paper. Maybe "Co-author was funded by Blank to edit the manuscript" is a middle ground?
The source of funding in question is the co-author's country's government - although unclear if it's a research grant or co-author's salary as a professor. In either case is it acceptable to "use" this money to edit manuscripts from previous work done and funded elsewhere?
First paper & graduate student, to finalize the context.
