> They would rather move to different technologies in case Java is abandoned.

They had the opportunity to do so for at least a decade now, but they didn't. Google, even after the massive row with Oracle, still uses Java extensively. Still has new projects written in Java(or running on JVM). Having a big legal battle between Google and Oracle would surely have dissuaded FAANGs from starting Java projects, right? Nope... You're flat out wrong.

> Java were to be abandoned they can easily migrate / rewrite

That's one delusional world you live in.

> It is not like current prod systems will stop working just by announcement.

And what makes you think that those big boys aren't going to be interested in maintaining JVM?
