Interesting find! There were also 48 states when that was written though, so we should probably take its current-day accuracy with a grain of salt.
Indeed, the nature of VOA has changed over time. During the Cold War it served to bring accurate news to countries behind the Iron Curtain and fight Soviet propaganda. (The Soviet government jammed it during this time.) Obviously this mission has changed since then as well since the Soviet Union no longer exists.
Ultimately its current reputation of journalistic objectivity does not depend on nearly century-old records but on what we can see today; dedicated journalists and accurate reporting.
