I remember this being a controversy when the documentaries came out. I ended up watching the Hulu one when it came out, and was underwhelmed having already seen the Netflix one (which was quite well done). I suspect that this "controversy" was simply an attempt to get publicity for the Hulu doc (it succeeded on me, at least).
It's not surprising at all that a PR/advertising agency would have a lot of footage from the event they were attempting to promote.
