Leaving aside the specifics of this situation and the implementation difficulties, a corporate FOIA where legitimate researchers (and others like journalists) could get reasonable, vetted access to data sounds fantastic. It'd be great to know what criteria your insurance used to determine appropriate rate increases, or the history of food safety failures at the slaughterhouse that produced the meat at the grocery store.
Why would you take a moral stance against that (as opposed to the obvious practical stance against it)?
