I think that was the point. You need to give it to the journalists to interpret. When it's released raw they have less of an incentive to do so as they aren't getting the 'exclusive'. It can be covered by anyone. It also takes them time to analyse these things. The good journalists don't read it and write a story, they take time and do it right and investigate further. Releasing it raw brings it into the news and once it's gone out again it's unlikely to come back so by the time a good journalist has written a good report nobody will care.
