OSM Foundation does not buy imagery. The community just relies on what is made available to them: Bing, Esri, Maxar, Mapbox all make their imagery available worldwide, on top of that many state or local governments have freed up their imagery. As for street-level imagery there's Mapillary and KartaView, both relying on volunteers with smartphones. The most important stuff, and the real asset of OSM, is what can't be added with aerial imagery: POIs aong with their attributes, road surface, speed limits, turn restrictions, paths in forests covered by trees and so on.
