3b) I think the paper could be substantially strengthened and made more generally applicable through reference to existing frameworks and similar efforts. I am thinking particularly of the work of Fecher and Friesikie (a number of articles including the important "Open Science: One term, five schools of thought" but also recent work on barriers to data sharing in Germany). Christine Borgman's work on data sharing (Big Data, Little Data…) and more broadly dissections of incentives (European Commission Expert Group report on role of research evaluation in progress to Open Science, Metric Tide report) and potentially the literature around choices to public Open Access as well could be valuable. At the moment I feel that the article reinforces what we have seen in other cases, which is valuable. I think it would be stronger and more valuable if these issues were developed in those broader contexts.
