I didn't miss your point at all. I just think its unfounded. A closed Beta & the early Adopter open beta.
The NDA primary purpose is to ensure order in information release & to give pimax time to evaluate test results without premature press releases.
If you looked at the requirements the team laid out for testers. Leaders & reviewers are prefered. Closing Testing til completed & agreeing on a press release date is good business. Reviewers often compete to try & "be there first". The NDA levels the feild while also protecting pimax & backers interests a like & protects testers as well.
