I doubt this will be any kind of soul-searching moment for the OSM community. OSM contributors make use of hundreds of different imagery sources from volunteer, corporate, and government sources. Few mappers will be particularly interested in the nitty-gritty of the funding. If the imagery is available with a compatible license, it will be used in mapping. If not, mapping will still happen, possibly more slowly. (On-the-ground survey is always the gold standard.)
