It's all about ego and elitism... There will be a hierarchy and corporate culture that struggles to act-out when people work from home. And those at the top no longer feel at the top. It has frick all to do with collaboration and culture. It's about corporate politics and nothing else. Home-working equalises this and the top brass don't like that!
This is actually untrue in my experience. The people at the top are the C-suite, assuming the company you work for has IPO'd, RTO'd, whatever, that ticker symbol is a
FOR SALE sign. The people who own the company are the shareholders, the board is accountable to the shareholders and has a fiduciary duty to make them money. The CEO is accountable to the board -- or the chairman directly if the chairman is an executive chairman -- who, again, are directly accountable to the shareholders. Directors direct and approve actions at board meetings. Officers do, and perform the work. If the shareholders are unhappy with the company, they can exert pressure at an AGM meeting and get rid of the directors and/or officers who are failing to represent their interests.
If you're a CEO, CFO, CTO, C-whatever, you generally have very high compensation coupled with very high stress levels and no life, because every problem is
your problem. You can't pass the buck onto anybody else, because even if the issue was caused by some other person or group of people, indirectly, it's still your fault, because you're responsible for all of them. You, personally, are failing, not the entire strata of subordinates and constellation of departments supporting your role.
In this particular instance, as has been mentioned myriad times within this thread, I think Apple's biggest problem is... WTF do they do with tEh Mothership they just spent an insane amount of money/effort/time building. They need live bodies to fill it up.
