Further to @ReinstateMonica's excellent answer, all of the points made need addressing, but none of that will happen until the company, and the employees, acknowledge that they have done something wrong. Without that, nothing will change.
They've feigned this realisation, twice, but it just turned out to be empty rhetoric.
There are many indications that the company and the CM team are blissfully unaware, or unwilling to believe, that they have committed any wrongdoing.
You can see this by the attitude of certain staff members on social media, lauding the fact that people are leaving in protest, and blocking people from being able to engage in discussion.
You can also see this from the attitude of moderators deleting Q&A threads, I believe the quote below sums it up.
So we get what we have here: a clear statement that this is how it must be. ...[snip]... So I recommend dropping it.
These are not the attitudes or actions of people showing remorse or contrition. These are the actions of people who have stopped listening, and are absolutely certain that they are in the right. They are saying that "this must be done", and are telling us to "drop it".
You can understand their behaviour, put yourself in their shoes for a moment. You've got to either admit to yourself that you've done some pretty terrible things over the past several weeks, or you can rationalise your actions, and justify to yourself that what you're doing is "the right thing to do".
So, to summarise: the current challenge is not for SE to resolve the current crisis. That cannot happen until we manage to get the message through to them, and to dispel them of the notion that they are currently taking the correct course of action.
