Yeah, this is clearly a fluff piece to associate two nice, fluffy British institutions - Harry Potter, and GCHQ - in a way that reminds people its not all about death, destruction, prejudice, using arcane methods to control people against their will, killing those not of your own race/culture, stealing their resources and covering it up so that an ignorant 'sub-class' of people can continue to live their pathetic, un-magical lives, etc. Oh wait. It actually still is all about that. Just warmer and fluffier.
