That's an interesting video and article, although the way they conflate backing with early access seems unhelpful.
To my mind, early access is primarily a consumer experience. You buy something to say you were in there before it was cool, or to have the edge over the other guy come release day. Reviewing early access stuff as if it was a complete product makes perfect sense - it gives consumers the information they need to make good purchasing decisions.
Backing a project should be more like a shareholder experience - you put money in to a concept, have input at stages along the way, and eventually walk away with something that may or may not turn out to have been a good investment. So reviewing a crowdfunded game like a finished product doesn't make sense - for example, if the developers put a feature in one week to provoke a reaction, and a reviewer writes up a negative reaction, it becomes harder for the developers to involve the community the next time.
On the specific topic of Star Citizen, I'm not saying CIG are perfect, but I agree with Fivebyfive the big problem is backers not holding them to account. Things like 10 for the Chairman are a golden opportunity to make them really think about problems from a player's perspective, and while there have been a few really good questions, there's a tendency to just push them for ever more features instead of really thinking about the aesthetics driving the game. psyron is right that it's really difficult to channel antipathy into critical friendship. but some of Frontier's best decisions were forged from the most rancorous DDF threads so it's definitely worth the trouble
