Quite often, people make purchasing decisions on the basis of cost. They buy the cheaper item. This has an advantage that manufacturers are encouraged to be price-competitive, but it has a nasty disadvantage.
That disadvantage is that manufacturers may cut corners to make something cheaper. The manufacturers do not often state what they are doing.
If packaged similarly to the original item, one may purchase it by mistake. I was once suckered this way into buying a butter/margarine mix that was just about the price of butter, but that was not suitable for my mom and me.
The corner-cutting can continue for several iterations until the cheap item may bear little resemblance to the original product. Consider most so-called ice cream compared with the real thing. If you have not done so, this is fun research that you should get going on.
