For what it’s worth, many of datasets available in Rapid Assist are ArcGIS datasets for which Esri followed the procedure laid out in the import guidelines (wiki proposal page, imports mailing list announcement, etc.). In a couple cases I’m aware of, these import proposals conflicted with other import proposals from volunteers in the local community, so folks closely watching the wiki had to intervene before edit conflicts arose. Otherwise, there was very little comment from the community on the imports mailing list at the time.
Most if not all of these datasets are conventional GIS building layers at the county level in the U.S., so they’re pretty straightforward to characterize and review. The more contentious datasets seem to be the broader-scale ones that didn’t go through the same Esri pipeline.
