As much as those inside the freeskiing community want it to be 'for us by us' you have to remember that it is being presented on NBC to the an audience of freeskiing laymen. Right or wrong, the forums of NS are not the target audience.
This documentary - like the Olympics - is about being the first interaction many people have with the sport of freeskiing. For all the inside info and interviews with [insert-your-favourite-skier-who-should-have-been-included-here] you can track their personal projects, you know where to find them. As a corporate production, they had to stick with the easily packaged narratives rather than having a million talking heads only known to the core freeskiing audience. Stories are the best way to engage with people, so you want to use them to pique people's interest and get them excited about skiing, not scare them away and make it feel confusing, exclusive and cliquey.
While VICE do on the whole have a journalistic freedom MO, they don't have a money tree or shit cash so they will have to get fronted by corporate sponsors, who will have a say on the direction of the finished product. It is naïve to think that this is the first or only time that VICE has descended from its Mount Pious of gonzo journalism to fund a story it though was worth telling.
For the sport as a whole, in going big time/olympics/mainstream or whatever you want to call it, this is the sort of thing that will happen. I don't know whether it is a good thing or not, that's just the way it is, things'll never be the same, that's just the way it is, aww yeah.
TLDR: It wasn't perfect but I'd rather watch this than sit in a dark room with my thoughts. Skiing will be fine.
