I don't want to reply with a blanket statement, but a lot of the times senior management just doesn't understand how much work it takes to build complex IT systems and how a great team can make it happen. They see IT as disposable and expect anybody with some computer skills to be able to do complex work.
That makes sense for IT networks, annoying as it may be. But the article makes it clear they lost quality leaders as well, and the CEO should have fully understood and appreciated the impact that would have.
