It is a multi-cloud world
It is not going to be oracle or AWS or Azure or IBM or Googel, it is going to be AND. We move to a world where businesses use more than 1 cloud. And still have their own private cloud and their legacy. Unless you are fully bought into Oracle Azure or Amazon, having a propriatarry hybrid cloud reduces your flexibility. A true hybrid cloud is if you can move your workloads where ever and whenever you want. Not just to 1 cloud provider. So, yes I see a future for workloads in a Oracle or microsoft specific environment, but as always it depends on your workloads, your strategy, yout situation. Just make sure you stay flexible and can change when you want without disrupting your business. Today is al about speed. Getting locked down may not always be the best option.
