The thing to realize is that the culture is going to go very quickly from bad to worse.
As the cloud numbers don't improve, the layoffs will continue. Each group will be working to make sure someone else is laid off, not them. And within each group a pecking order will be established to make sure the manager's lackeys are always left standing.
If you thought there were dirty tricks being played before, it will be a free-for-all in the sabotage, humiliate and attack game.
If you don't want to be one of the attackers and you don't want to be attacked, you need to get out.
If you are 50 and think you will be waiting for retirement at Oracle, I don't think you are going to make it. The company is targeting the older employees. If you are 50 and making a bay area salary, you can be replaced by 4-5 developers in India. You may think you are the only one that knows an area and you are safe, but the management looks at the numbers, not your experience.
Better to update your skills and start looking. At least you will know what is out there before you get your walking papers.
