Why does the Capitol make things public and why do they hide so much too?

The way in which the people in the Capitol act shows that they want to control all news media; this is a propaganda technique and is designed to keep the people submissive. Punishment is shown as a deterrent to keep the people in line; anything that might make the people feel good about themselves is often kept hidden because it would increase their self-esteem and make them feel that they have rights.
