They were told many times that the systems needed to be upgraded, but did not because ignoring it would mean higher short term profits. When executives choose profit over responsibility there is no negative consequence. So for example when there are crashes or massive delays due to negligence, the executives should possibly be criminally charged or companies need to pay very high fines. If the consequence is any less than the increased profit, then they will continue to choose the increased profit.
