> Classic instance of the sunken cost fallacy fallacy (not a typo). They prefer to cut their losses and forget about how much they spent recruiting those people.

The Sunken cost fallacy would be to retain those people because of the costs irrevocably incurred (sunk) recruiting them, employing them to date, etc. Apple are (apparently following a theoretical economics position) considering the prospective costs going forward of keeping them, when they no longer have an obvious future revenue stream, and would still generate additional redeployment/retraining costs
