Oracle is only one player in the Java ecosystem. OpenJDK owns just about everything now, and most organizations are going to get support somewhere besides Oracle. There's been some good recent innovation with Java, and I think it'll continue due to the new accelerated release schedule.
That reminds me, I want to experiment some with AOT compilation and also the new GC plugins.
The bigger reason is one word: Oracle
Whether you go towards C# or other companies... Oracle is a horrible company.
