We don't want to deal, or like/enjoy dealing with this pesky employee stuff. We don't have the time, energy, or enjoy it, and they'd rather do something else with their time and money.
They are in a position where they either crack-down on their culture to more of a corp like, and appear to go full evil, or be even more lenient, and risk small 'intolerant' groups or activists taking over and creating disruptions to the business. Whatever they do at this point, they will be either painted as the bad guys in the media (if they go full on evil corp); or the 'dysfunctional' company, if they allow even more discontent and become more 'college/academic like'.
Basically, their employees situation is becoming such a PITA for them, they'd rather not deal with it and quit the company and do something else, more interesting, instead....
They realize that they just don't enjoy dealing with the creature/organization that they created.
Basically, it is the CEO's version of: "it is not you, but it is me" line of break-up, and we all know what that line means.
