That is all large companies. You throw money at something and see how it does. That is how they should function. Why keep a product that isnt making you money? Sure, they could continue iterating and maybe just maybe some day it makes money. Or they can jump to something more potentially lucrative in a shorter period of time. As companies in highly competitive markets. Markets change so fast. Any company that stagnates will get left behind. And apparently it is proven that scrapping something and using those resources elsewhere, is more profitable, than sticking with something long term, since so many large companies adopt that approach.

A smaller company may only have one product, hence they stick with it for as long as it is profitable.
