What? What makes you think this is unacceptable in the US?
I think most Americans prefer to be independent and not have to ask someone, but it's not really that rare.
And many hikers care A LOT about hiking and their maps. Hiking and cycling data in OSM is extremely good, as result of many such people being interested in project - as mappers and as users of data, including software creation.
