I don't think it means that. Sure, they're not going to run strongly anti-American editorials, but we're talking about news reporting here, and they don't seem to finch at reporting news that doesn't make the US look good. For instance:

This article repeats criticisms of US police actions against journalism and carries this gem: "“Abuse of power against journalism is really as old as America itself,” Wheaton said. “It’s an eternal struggle between journalists trying to expose and power trying to hide.”": https://www.voanews.com/press-freedom/police-response-press-...:

This article (republished from the AFP) is actually not too different from a certain type of subtle anti-democracy propaganda you'd see on CCTV (i.e. selectively emphasize foreign unrest to make Chinese authoritarianism look good): https://www.voanews.com/usa/timeline-us-race-riots-1965

They have an entire category dedicated covering one of the biggest American domestic problems (which, IMHO, doesn't make the US look good): https://www.voanews.com/usa/race-in-america

This article reports on some harsh criticism of the Iraq war: https://www.voanews.com/europe/british-inquiry-finds-iraq-wa...

This article does not paint pretty picture of the war in Afghanistan: https://www.voanews.com/middle-east/us-war-terror-kills-near...

This article (from a US conservative website) criticizes VoA for not being pro-government enough, and carries another gem: "The viewpoints generally expressed in these Voice of America articles are those of demonstrators, protesters, and rioters, and indistinguishable from coverage in The New York Times or The Washington Post.": https://www.heritage.org/progressivism/commentary/the-voice-...
