My experience is that, at my first job out of college, I found out while learning SQL on the corp dev sandbox (specifically allocated for prototyping and learning SQL) that one of the functions I'd invoked had been part of some special function that we hadn't purchased. Not having purchased it didn't mean that the function was removed or deactivated or paywalled - instead, it meant that it would work and increment the "number of times this feature has been used" flag that the Oracle auditors could have used to charge my company millions and millions of extra dollars because we were using the feature.
