Pinned straw:
Another thought I should add when looking at these partnerships, I look at some of the tradeoffs.
The larger party giving the offer ie Oracle or Larry J Ellison, usually wants something in return.
In this case, I think Oracle also wanted all of Prophecy's existing customer base moved to OCI and not just the ones that needed the move therefore it was worthwhile creating the special partnership. This means Oracle gets more revenue from new customers going into OCI from Prophecy.
In exchange, Prophecy wanted access to potential leads from Oracle's OCI user base and perhaps knowledge synergies.
At the moment, I think the partnership may have cost more to Prophecy than Oracle via the unexpected additional usage fees and it doesn't look like Oracle provided much assistance or even compensation which isn't a surprise. Oracle has a notorious reputation for being aggressive in everything it does. Also a few unhappy customers won't do too much damage to Oracle.
So the relationship between Oracle and Prophecy could be another question.
Instead it may be better for Prophecy to highlight the Oracle connection from their own presales rather than wait on leads from Oracle?
I may sound a bit salty and negative being a former holder. But it is also important to set a few expectations and be aware that it is not always a bed of roses dealing with a larger dominant party.
