I don’t think the corporate mindset of the Boeing company or FAA Aviation Safety is easily changed back. Managers were hired to fit it and support it.
It didn’t just happen all at once 20 years ago, it was a gradual but accelerating change over decades. There were key milestones in the 90’s and since. People fought it, raised alarms over it, were silenced, to the detriment of their careers and many left.
