Yes.

And your risk of finding that all the code you've created using a proprietary tool that runs on top of a proprietary platform owned by another entity is greater than just using the tools provided by the platform vendor who controls "the stack" of software below any other vendor providing an add-on.

Basically, (in this case) Oracle can break 3rd party add-on tools and programs anytime they want or make them operate in a suboptimal way by changing their product below. Oracle, Microsoft and other platform vendors have repeated done this in the past.

So buying cloud based or closed source tools that run on top of other closed source products controlled by another entity is a poor bet.
