Because B and C would not contain the same facts. Every map source has
unique errors, some of which are put there on purpose. Streets that don't
exist, names spelt wrong, with the wrong road type, etc. It's not hard to
show where data comes from, if you copy a lot of it.

The third street I ever mapped, just down the road from my house at the
time, has slightly different names on the road signs, the local street
atlas, and google maps. I have no idea which of the three is officially
correct, but OSM has what's on the signs.
