I'm thinking this might not be that bad.
Remember, this game is kind of going under the radar right now (Heck, I didn't even hear of this game till a week ago.) Most gamers still don't know that this game exists. I feel like they could get away with this, as long as they are prepared to launch a massive marketing campaign whenever they decide to drop the NDA. This way, they can reach a lot more people, who haven't heard of the game before, when the game is closer to a finished state, and actually looks good, with servers that aren't lagging anymore, with more features and less bugs.
It seems like this is kind of what JC wanted, too. From all the videos and text I've read on this game, it sounds like JC didn't want to make too much of a fuss while initially funding this game. He stopped the crowdfunding for a time, when he felt he had enough funds to go ahead with the project, and he wanted to avoid adding stretch goals and feature-creep, instead wanting to focus on getting the initial game ready, with what he did promise would be able to work for the release, and then focus on other features later.
Now, they will probably loose some people who already pledged, but that is only a bit over 30,000 right now, much less than the tens or hundreds of thousands they could pull in later.
