Every news medium, even you as a human being, makes intentional and unintentional selections on what to publish or not. As long as the published documents are not fakes (and independent sources verified them), motives are secondary.

If what is published is true, projecting motives in the publisher are an obvious attempt to distract from the message by questioning the messenger. The message is a fact, your interpretation of the messenger is at best guesswork, at worst fanfiction.
