Oh definitely, timezones do throw a wrench in things a bit, but there are easy ways around that usually, splitting engineering teams like the way you described is a pretty good workaround.

I completely agree that jobs that just can't be done remotely obviously shouldn't be, but any job that can be should have the option available. I just feel like most of the work from home backlash comes from people who cannot do their jobs from home and managers/executives that just want someone to babysit, usually in order to justify their own professional existence. It just seems like a lot of "crabs in a bucket" behavior.
