America.
Retailers are allowed to disclaim the merchantability and fitness for any particular purpose of the items they sell and most do. The customer is free to refuse, of course, via the simple expedient of going away and buying it somewhere else.
This is partially a blame-shifting exercise to reduce costs, yes, but it's also a shield against the ceaseless horde of dipshits we have in this country who will willfully misuse a product and then immediately try to sue the retailer they bought it from when it doesn't work or they hurt themselves with it via their own stupidity. It is much easier from a legal perspective to make a blanket "we don't imply this product is applicable for any purpose" statement vs. having to explicitly predict whatever cockamamie thing someone might try it on and have to say "no, moron, that chainsaw is not suitable for cutting bricks," etc.
Read all that fine print on the back of your receipt some day. You will be enlightened and, most likely, also infuriated.
The nomenclature I always hear is, "Experiencing a higher than expected call volume," and since no one can prove how low their expectations actually are there is no crack in which to insert the prybar of legal complaint.
