It's as if the relationships between the team are much different than with direct management and the disclosure happens privately between middle management and by the time they're gone, the team is left clueless.
I think we need to bring more empathy into the workplace. Especially the remote workplace. I operate on the premise that everyone is battling problems that you don't know about, but even knowing a generalized detail can help in the long term. It takes courage to be vulnerable which not many are willing to do in the workplace, but helps teams become closer and more caring in the long run. It's hard to give bad news, but it's even harder on everyone to say nothing at all.
