Java's popularity is decreasing because Oracle is charging for Java / Java support.
Now, because of this, Oracle will be earning less revenues from Java subscriptions.
The whole idea of Oracle was to earn money from Java but instead of paying, people are moving to other computer languages like Python.
So, anyways Oracle is not earning much money from Java (so why not make all Java versions free again).
If a computer language is not free, people won't use it.
So, I am requesting Oracle to remove all charges for Java and make all Java versions free again so that Java may become popular again.
