this will obviously depend on the individual case, but in some instances in Europe I have seen the published open data boundaries were simplified geometries. Just because the original datum was precisely acquired doesn’t necessarily imply that the published open data (often derivative data) is super accurate as well (our own errors in the transformation of the data during the import aside).
