Is there any info on why any of this happened?

Yes, a very vague official statement by the board and that's pretty much it.

is this the board actually trying to do good and Altman ...

The board's official statement made it seem that way. And this article kinda supports it (making it look like MS wants Altman at OpenAI so they have better leverage). But also the chairman of the board stepped down, which is unusual to say the least.

Not only is there more story, but also the story could be completely backwards because we have so little info.
