It's quite normal, unfortunately. Nobody trusts their employees in a $44 billion company, definitely not in the wake of a highly-televised hostile takeover. They have the MDM software, they intend to lay off the employees anyways... there's no wrongdoing here as far as I can see. This is just how they do things outside the startup sphere, it's not like the CEO is going to schedule you a final Zoom call and have their receptionists bring you a bouquet of roses.
