Pulling the emergency break promising to improve a situation will in general not build any trust unless the mea culpa also includes:

1. An analysis of what allowed the situation to get out of control to begin with

2. Systematic changes to prevent it from happening again

Otherwise you will just be in the same situation again in 3 years. And neither is included in Microsoft's messaging here.

I don't really see that happening here.

Microsoft doesn't have any trust to lose, and they won't be gaining any by this move.

That is the one advantage they have in all of this. Their public image is as bad as it can get.

Microslop is saying “I’m sorry that you’re offended” and will continue to abuse their users. All of this is a PR campaign to fix their image so that they can raise more money.
