While true, most enterprises have ways to silo and encrypt their data on non company controlled devices.
Android does something like that when you install ms office apps with administrator controlled policies
Fuck their data, what about my own? That pest of an app is not getting onto my device. And neither is anything else that gives an employer any control over my device.
A totally reasonable stance.
For clarity, the android feature essentially makes a work dedicated partition on the phone. Their management app can manage that partition, and for the purposes of data movement it’s essentially a distinct phone.
If they’ve set it up correctly they can do a remote wipe without touching your personal data.
In a lot of cases the drive to have users use their personal devices rather than employer owned ones comes from the users, not the workplace. Only needing to keep track of one device is easier in many cases.
