As someone who did an AMA for my Birch device, that is frankly an incredibly selfish attitude. I got people who thought I was some sort of employee of Purism just because I was willing to answer questions and did so nicely, and then people got upset because I didn't post things they wanted (and spread the exact sort of non-sense you are spreading now).
Publishing any sort of video takes a non-trivial amount of time, especially when one has never even attempted to try doing so before. The owner of that device isn't being paid to put that up there. I really don't blame the owner one bit for not wanting to do that, especially when I see attitudes like this. I also don't blame others for NOT wanting to do forums posts like that, when there are attitudes like this.
