Think of it this way... you can make all the demands you want, you can bitch and moan for months/years if Pimax doesn't deliver; but what is this really accomplishing? People have been complaining about transparency and details regarding the 5k/8k since the kickstarter ended... and what has all this complaining accomplished? The answer is nothing.
As people sit here and complain complain complain and make demands, all you are doing is stressing out the creators, and decreasing their chances of success. You can sit here and push your values on them all you want, but clearly they aren't listening. You have essentially paid for something that Pimax has no legal obligation to provide, and yet so many people demand answers and info and refunds even though Pimax doesn't even have to entertain any of it.
Considering the situation (where you made an investment in a product that has yet to be released), I can see why people would be frustrated/craving more information, however you have to understand that no one is legally obliged to provide it to you. You can scream and complain that Pimax isn't communicating enough, and isn't being transparent; and while this may be true there is nothing anyone can say to change the fact (read through the forums a bit and you will see this is true, look at all the posts by @SpecsReader nitpicking and demanding information and look at all the responses he got from Pimax).
The best course of action is to wait it out patiently and not stress the creators to the point of madness. While you may not like how they are running the show, you should accept the fact that you aren't in control of this situation. We all want a fully functional, finished headset as we were promised, but raging at Pimax is only creating a toxic environment here on the forums and is completely discouraging any productive conversation that could be occurring.
If/when Pimax delivers a broken product/doesn't follow through on their promises, they are just shooting themselves in the foot. At that point I think it will be totally justified for people to freak out and bash Pimax to the fullest extent.
