The problem is that all this looked more like a PR action, not a real physical experiment as it supposed to be. For example, we saw how the astronauts brushed their teeth, but we never saw how they left the Apollo cabin for the lunar module, how they made all those complex movements (do you all know that they needed (all 7 missions) to turn 180 deg in space and lock with the lunar module that was going behind ??), etc.
all we know is that many pictures bear the traces of staging/postprocessing and that some 380 kg of moon rocks brought as the only real evidence have disappeared in the NASA archives.
