Even for products without CR/WC-levels of traffic being thrown at them do this.

My parents had silverware they liked, 10-ish years later we had lost or chipped a handful of them and they bought replacements. They look identical and feel identical…. Except the new ones clearly used lighter (read: cheaper) materials and then put a weight inside the handle to make them feel the same. The problem is that the weight is not attached well and can become detached and start sliding around making the handle rattle when you turn/invert it.

Just so irritating to know that effectively every product/brand will do this in the end.
