What would MDM enable on Linux that isn't already covered by FreeIPA/IdM combined with ansible?
Plus having a cross platform MDM would allow an IT team to manage a fleet of end user devices without having to become experts in each of them. For example, the MDM could have push button "erase this machine", etc
Not sure how I feel on the second point. Managing Linux at scale, aside from the laptop point is pretty easy. Maybe companies need better help desk employees.
