And Kübler-Ross did not describe a linear progression of grief. It was meant to be enough of a framework to start conversations, to put experiences in perspective, to help reflect. And plenty of times, life still has to go on even with devastation -- no time to grieve and reflect until crises has passed.
The wording of the co-founder's comment and the post did not strike me as grief. They are calling out enshittification without trying to burn bridges and requesting help.
