It is presumably a rehashing of the old saw that the LM was so badly built that it couldn't possibly have worked because many of its its external features are made of foil and tape and only loosely attached, ignoring the fact that as it never had to face aerodynamic forces the exterior didn't need to be sturdily built (and therefor it wasn't to save mass) and that the actual internal structure is much more sturdy (though still no more than is necessary)
