Yes I was going to say something similar because articles like this make it seem like a mysterious problem. In reality the reason this happens is because people want profit and the most profitable thing to do is unfortunately to drag a problem out. This literally happens even with individuals, you can give someone a task and he will try to explain to his teamlead that he has to research this all day even though he already knows the answer and he might do another hour on it. In general we have a problem that solving things quickly and permanently is not profitable for the individual/company.
