Yes, Oracle, the company that sues people for breathing the same air owning Java is an issue.
Maybe I am uninformed, but you haven't made a good case that there's any truth to that.
I think my question is, do most Java developers really know what goes outside of their window? Every language has a good story for web apps these days. The web is ubiquitous. You can write in Phoenix, Cowboy, Rails, Sinatra, Express, "net/http", Django, Laravel, Flask, Rocket... Java is literally middle of the pack at best. So that's not a compelling reason to use Java. So then we have to look at the rest of Java. Is there anything else in there that would make it better for web dev than a simple Go/Ruby/Python/Javascript/Rust/Elixir app? No? Ok, then let's not use Java. Java excels at being mediocre at everything, but the best at nothing.
Ask Twitter how their Rails apps is holding on.
A warm JVM is faster than a greased millenium falcon.
There is a lot of software running in this world. Some of it is very long lived.
Other open implementations exist from Amazon, IBM, Microsoft, Zuul etc. And they are all using the JDK name which isn't owned by Oracle.
If Oracle were to die or become aggressive the Java ecosystem would just move on and not skip a beat.
For people actually working with JVM and the languages on top of it, nobody really is worried about Oracle. The way the licensing is set up, they just don't have enough power to coerce people to use their version. It would kind of be like the SCO case if they came after it. I think they went after Google for Android simply to protect their IP, and that one they even "lost" (which detracts also from their possible future lawsuit on enforcing Java licensing)
