Arguably I'm not quite done mulling over this, but I've started to wonder if the insistence that work-from-home isn't working, isn't an indication of failed management.

While software developers and similar roles have rather easily adapted to working from home, some managers haven't been able to keep up. I suspect this is because many of them weren't great manager to begin with. They struggle to do project planing, follow ups on current tasks and keeping the job queues full. Forcing people back into the office is an attempt to revert to an environment that hides poor management skills, even if it's worse for everyone else.

The success of "work from home" seems to me to be very much dependent on the management and culture of a company and Facebook may simply not have a management layer that can deal with developers not being at the office or working at odd hours.
