Even if it was legal to copy names etc from in copyright published maps (which may depend on the local legislation), we only want to use sources which we have either been explicitly allowed to use in OSM (and have a compatible licence) or have whatever the local equivalent of public domain status is. That said, my personal opinion, besides copyright issues, is that it is counterproductive to simply use the same sources that everybody else uses. One of the greatest values of OSM is that it is an independently surveyed dataset and doesn't copy the same errors everybody else has. Further we should really only enter data into OSM that we can long term maintain and keep up to date, in other words information that we can survey ourselves. Note: there is no such thing as "official" in OSM, only a rough community consensus that is open to interpretation.
