That's a bit harsh. I suspect most people simply don't understand the dynamics of objects inside boxes. (There was some discussion on here about this a while back.) Manufacturers packaging is usually preformed to provide appropriate protection and restraint, but even if you know what is needed it can be hard to achieve with diy materials. Some of it is also down to luck in so far as whether the box gets handled fairly well or suffers the throwing to the other side of the room fate.
I don't think so......if you are selling an item, it is your responsibility you wrap it up for every known problem. It is your job to lessen the eventualities to an absolute minimum, and from looking at the minimal packaging agents within the box as shown, that just wasn't the case.
I participated in sending 4 tugboats to 4 different buyers earlier this year, and we packed them so well that even by MYhermes standards of delivery and handling, NOT ONE was damaged in any way whatsoever. so it can be done with care and method.
