Use OpenJDK (or similar) and you are free from any Oracle shenanigans.
And all the other variants ultimately just repackage it. So if oracle doesn't care about destroying the Java IP, it definitely could cut everyone off from updates going forward.
I don't think they'll do so however, MySQL is still freely usable too, right? And that's oracle IP too.
Might change if they ever get into financial troubles, but that's the same issue with all languages and frameworks.
Sure, that could stop to maintain it, but would put the power immediately in the hands of other companies with a fork
That said, you always have oracle's greediness...
I have a feeling all those companies / orgs would band together to maintain it.
BTW, I don't dispute that Oracle is greedy, but I find the suggestion that Amazon, IBM, Google, MS etc. are any less so laughable.
It is used everywhere. Just among the faang companies, Apple, Amazon, Netflix and Google definitely use it at scale, and they're just the tip of the iceberg. Taking away JVM updates would almost be a company-ending event for them, and they definitely have the resources to keep it alive if Oracle ever dies.
