But without any physical explanation. Their only real explanation is that they sell stuff that fits in that place,

Their statement that "the sheetmetal chassis will no longer flex along with the rubber mount" is nonsense. The rubber mount only allows the sheetmetal to flex with a force corresponding with the force exerted by the rubber bushing, being the rubber's spring constant or Young's modulus.

Young's modulus for aluminium is about 69GPa, for rubber its somewhere between 0,1 and 0,5 depending on the shore rating.

This is a good example why you shouldnt trust explanations by companies that have a substantial financial gain without going over it by yourself. They're trying to sell. Not to help.
