If I remember correctly, Oracle has a licensing scheme if you want to build and release your own JVM. Java SE always has significant more usage in production thanks to Android, Kotlin, Clojure, and Scala. While Java EE does get used a lot in more conservative large enterprises, the alternatives developed to overcome the inherent complexity of EE (Spring, Hibernate) get a LOT more. Java EE is big, but Java SE is even bigger.
