I think there's a difference between, say, NASA tweeting about its mission and other examples the article uses. If NASA isn't promoting the mission it's been tasked to do, telling us about their progress and their challenges, then who will? NASA telling the public this stuff is part of their job, so the public knows. Also, it's not hard to deduce what NASA's slant on going to space is: of course they're for it. It's easy for us to interpret the message in light of the messenger.
