Good questions Mitch.

I don't know the answers.
Can only speculate that FBR is not able to record a video of the HX stacking some bricks yet (because as a system it isn't functioning E2E yet)......
I cannot think of another reason that is in the interests of share holders or FBR to "not" publish a video.
FBR has no competitors in construction robotics that would benefit from seeing a video of the HX at this stage of its development.
Those 3D printing construction companies wouldn't learn anything useful.
The company behind SAM is many years behind FBR in terms of robotics, that it wouldn't matter if they saw HX laying some bricks for a wall.
