it would not surprise me to learn that in fact 80% of Oracle employees have turned over in five years (assuming the average employee is staying less than four years, which is consistent with what I have observed at similar big tech)

I once interviewed with Oracle Cloud (when it was going through its big-rewrite), and I was told the goal was to staff it with entirely new, not-Oracle people...the conclusion being that the first incarnation of Oracle Cloud failed partly due to staffing it internally

It's the few at the top (Larry, Safra, etc.) that set the tone. They won't be around forever but they have a few years left.

We may be confusing internal culture and political environment with how they address the customer. I'd look to info from customers, not revenue figures, for the customer experience.
