Oracle launches the right beta programs for its licensed software - database, application server, e-Business Suite, etc. These programs are closed, for invitation only.
But it also has many by-products for which it does not charge, such things as SQL Developer, JDeveloper, Application Express, SQL Dev Data Modeler, etc. These products have nascent enthusiasts. Oracle uses its zeal to cover beta costs by releasing Early Adopter and / or Release Candidate software versions. In return, early adapters gain access to the new features they need, and possibly the ability to create products while the software is still malleable.
