Unfortunately, this project creator hasn't provided any proof that the money was spent working on the product. If there were photos and records of work and progress being attempted, and at least some communication with the backers along the way, I suspect the tone and deposition of the comments would be different.
It's a lot to read through, but there's pages of people just asking for transparency to see the status and to understand what challenges were coming up. There's just as many comments from the creator that things are going great and we should be ready to ship in no time at all.
Trying out a new project or product and failing is one thing, never attempting it and running off with the cash is a different matter entirely.
I agree that they should be posting updates to prove the money is being put to use. However looking through the comments I see a number of people referring to the backing as a 'loan' and complaining they didn't get the product 'they ordered'. I think it's clear this 'company' has screwed people but backer expectations are also completely wrong and Kickstarter needs to solve that problem. People seem to think if they give you money and you fail they can get a refund. That's not how Kickstarter works/should work.
