Isn’t that a pretty widely used strategy? Eg. Uber pretty much lost on initial rides (maybe even now), so it’s hardly big evil Oracle, but big evil capitalism.
Except that Uber's product is a commodity. It's far, far easier to switch to using a different ride sharing app than it is to switch to using a different database. Especially for a large organization.
