what "the degrees to which an individual peer service or goods provider can elect to work for a sharing platform" mean?
"The degrees to which an individual..." means To What Extent or How far will they go to achieve their goal. I can see how your context mashes this phrase together with others until you are ready to break out the protractor, but neither Degrees nor Radians are used here. The degrees or extent to which a provider can work, is the meaningful part.
