Cost vs reliability was what they were looking at when selecting parts. A part that lasts 2 years is a problem, a part that lasts 80 years is a waste of money. They were looking for parts that would last 20 plus years and be cheap to buy.
Spending 0.25c for a better part doesn't seem like a big deal, but when you are buying a million of them and buying for dozens or hundred parts for a given model times the units sold, fractions of pennies add up big time.
That cap is a non critical bypass filter, literally anything would have worked.
