That's not very helpful.
I'm reminded of Michael Moore in "Roger and Me" standing outside of GM headquarters with a megaphone asking for an interview with the chairman. Michael Moore wanted Roger Smith to explain why GM was shipping so many jobs abroad. It was a fun movie, but Moore never did get that interview and the jobs continued to go away. Something tells me that the entertainment value of your grievances will not rise to that level in either significance or entertainment value, so I think making a documentary is a non-starter.
You can vote with your money, but all the companies are similarly obtuse. For instance, many complain about the ability to even use MLU on Canon DSLRs. Also, sometimes it costs more to vote with your money as the alternatives are more expensive (for example, buy a Zeiss lens to replace one of your equivalent Nikkors).
You can write letters, organize petitions, start threads at camera forums, etc; but that will be even more futile than the vote with your money approach. Nikon is not a civic organization and does not respond to civic approaches. Essentially, you have to convince Nikon or any other company that if they do what you want them to do, then they will make more money from it. The only way you can make that case is to speak their language, and their language is embedded in their culture.
Nikon believes they know something you and others who complain do not. It is reasonably arguable that they do not, but they will wave years of engineering experience and their currently strong market share in your face and go on doing things the same way they've been doing them. Many of us (myself included) have a laundry list of things we want Nikon to improve, and that list goes well beyond firmware fixes; but no matter how easy it would be for them to fix any issue we have, issue by issue we just have to deal with it and not waste our time imploring Nikon (or any other company for that matter) to adjust their products to meet our specific needs.
I'm sorry I couldn't be of more help.
