Yes that's the better description than a "coup".I wouldn't be surprised if this is more of a graceful transition of power in a way that allows people to bow out and avoids people losing face.
But part of the lesson is they don't want to completely rework 7's design and don't need new designers. Their path going forward seems like it will be a bit whack-a-mole but with a genuine and sincere new leadership to hack away at the problems. I don't think that's "enough" but enough gumption and creativity can do a lot.
