Leon, in my opinion this is totally on the sender. I've sent hundreds of packages through the years using all carriers and have never once had the recipient receive a damaged package. I yet to see anyone who packages stouter than I.
Going in, if a seller is sending something as fragile as this and doesn't take the precaution to package it up with more than a piece of cardboard knowing darn well these things get tossed around by not only people, but machines as well puts the blame solely on them.
Now if this item were to have been packaged like a Sherman tank yet still arrived damaged it would be a different story. Not the case here though.
My two cents.....
