Larry must be desperate
Let's face it: Using a public cloud offer always comes with a measure of lock-in: A spectrum from just "convenience lock-in" where the effort of moving a workload to another provider or self-hosting is just a resource-costing nuissance up to a "systematic lock-in" where you need to rebuild a lot of components to make it even possible to move to a different vendor. We have come to accept this and many (if not most) mitigate as good as possible.
The only reason we are willing to even consider accepting it is an uneasy trust not in the vendors, but in the market forces moving them: If one cloud vendor were to start screwing his customers more than the pain threshold, he would have a very hard time acquiring new customers and stall his growth - which is very near to a death sentence in an industry where economy of scale is a major effect.
There is one thing though: For many of us (and this definitly includes me) this trust does certainly not extend to Oracle, whose business model is sometimes perceived as "lock, screw and blackmail". And while this does work with (mosty legacy) applications that are tied into the main Oracle Database product, the idea of beginning or extending such a relation to cloud hosting does not go down well with IT departments. And forcing a product into goverment contracts via the courts doesn't inspire confidence as well.
So Larry made a cloud, and nobody wants it - if not coerced with one of those beloved audits, basically nobody signs up. Beware of a furious and desperate Billionaire!
