Starfleet seems to have an interesting relationship with the media, giving privileged access to reporters who are willing to make at least some of their subjects look bad. Low-ranking officers also evidently know a whole lot about weird and embarrassing things that other crews have done, so at least basically mission logs must be relatively easy to access.

There are counterexamples, but on the whole, it doesn't seem like the kind of information that would matter to that magazine is controlled much at all.
