None of those arguments really wash. If an industry depends on hiding its typical (or even exemplary!) operations from the general public, because of fear that people might not buy the industry's products if they knew what was involved in its production, that only builds the case for making sure the public knows what's going on. That reaction is basically proof that something the public is interested in, is being hidden.

The public interest absolutely trumps some sort of business-model protection. In fact the only exclusions I can think of to that involve trade secrets provisions, but typically there IIRC there are fairly narrow definitions of what can be protected.
