Our disagreement may be partially semantics. You seemed to be using transparency as some kind of blanket term for all information discovery.
Transparency is authorizing disclosure of as much material as possible and acting out in the open, it's voluntary. When a restaurant has an open air kitchen that is visible to patrons, that is transparency. Transparency is putting things on display in a live and uncensored fashion so that people KNOW the reality because it is on display, as if through a transparent window.
When an employee of a restaurant leaks that they have an insect problem that is information but it is a leak of NON-TRANSPARENT information.
Different parts of our government are positioned to challenge each other, we have freedom of information requests, we have whistleblower programs, and we have technical measures that people can use as a means of last resort to disclose things government doesn't want us to know but we don't know if that information is true or represents a complete picture.
Transparency makes it far more likely the restaurant keeps a clean and sanitary kitchen in the first place and reduces the possibility that such a leak is true. The restaurant is taking a risk by making things transparent. You ARE going to see someone scratch their nose or backside now and then. You ARE going to see the three dishes they screwed up before bringing your plate.
"How does media do this though if they can only report on what the government authorizes?"
The claim the government required them to commit to not reported unauthorized material instead of acknowledging the policy was itself false information. The government making media who reports what they don't want stand in the back of the line instead of being first in line when they issue a press release doesn't stop anyone from reporting anything. They just one get first shot as information the government authorizes and since they've cranked transparency to 1000% the probability of there being stories in within the live stream the government is authorizing is way up.
