Certainly that's a political problem, but I'm not convinced that releasing data will contribute to that. There is certainly no shortage of inaccurate information being sent by people in news media all around the world. I think providing more information that is raw in terms of data and relatively free of interpretation makes it that much more likely for people to be able to see information at the source and to make up their own mind, in one sense.
Talking about repurposing is also important. One of the defining facts of this age is the glut of information we're all faced with, which makes it easier in some ways for misleading things to get in. One of the great benefits of data, meaning something that is computer-readable, is that you are that much more able to search through it, to get the bits that interest you, to repurpose, to find what's relevant to you.
It's definitely a challenge of the times with the amount of data we are facing and trying to make accurate sense out of it, but I think more information from government is a good thing.
