If it makes you feel any better (it probably doesn't), the development of OpenJDK and the Java language itself is also mostly funded by Oracle

Java is funded by Oracle, all of it.

People parrot to use OpenJDK without understanding it is mostly Oracle employees working on it.

And if you dislike Oracle, the other minor contributors are Red-Hat, IBM, SAP, Microsoft, Alibaba, Azul,... which for many HNers are the same.
