They even created Kotlin to help sell InteliJ licenses, cleary they are having an adoption problem outside Android.

"The next thing is also fairly straightforward: we expect Kotlin to drive the sales of IntelliJ IDEA. We’re working on a new language, but we do not plan to replace the entire ecosystem of libraries that have been built for the JVM. So you’re likely to keep using Spring and Hibernate, or other similar frameworks, in your projects built with Kotlin. And while the development tools for Kotlin itself are going to be free and open-source, the support for the enterprise development frameworks and tools will remain part of IntelliJ IDEA Ultimate, the commercial version of the IDE. And of course the framework support will be fully integrated with Kotlin."

Why is it that only you say this, everytime the same user handle, cherry-picking things out of context.

The part that you quote, is understood clearly that: for a company to do a thing (develop a programming language, for free), that thing need to tie back to their bottom line somehow.

That is not the same as "in order to sell more IDE licences, we need to create a programming language". That is such a roundabout way to think, why not just make more IDE variants for the uncovered languages, and not have to deal with promoting this entire new thing?

At this very moment I am working on a product with a kotlin back-end and flutter front-end.
