He who defects first defects best. As company finances worsen and layoffs increase, there will be less to go around in terms of layoff packages; there are a limited number of lifeboats, and those who got to them first were the ones who survived, so it's better to be let go now rather than later.
Sure any CEO/CFO can easily shore up the books in the short term by mandating layoffs, but with billions going up in smoke in the form of share buybacks/dividends, no real growth drivers, and the potential dismantling of the QTL licensing model, you can foresee that we, like the Titanic, will founder.
