I don't know of too many companies that would spend tens of thousands, hundreds of thousands, or perhaps millions of dollars to "move off of Java", i.e., rewrite everything from scratch in a different language.
They search for alternatives, like using Amazon Corretto - a free, supported version of Java based on OpenJDK. Amazon is taking security fixes for newer OpenJDK versions and backporting them to Java 8 and Java 11 so that companies with a significant Java investment can continue to use those versions without paying the high support costs that Oracle is charging.
A lot of people don't understand that OpenJDK is controlled by Oracle. It's Oracle's developers supporting the project. And hence, the lack of security fixes for older OpenJDK releases.
