While I understand your focus on developing your IDE, I believe the general acceptance of Kotlin is in the best interest of both JetBrains and the programming community. While I wish to use Kotlin on my work projects, I cannot convince managers to even consider Kotlin since there is no Kotlin language server to support integration with a variety of tools from a variety of vendors and the Open Source community. IF JetBrains were to play nice, it would help the adoption of the Kotlin languages. Sure some members of the team would use tools not built by JetBrains, but I and many others would purchase commercial IntelliJ IDEA licenses, because it would be the leading tool. So overall, I believe adding such community focused capabilities would help your business as well as the greater adoption of the Kotlin language.

Thank you for reading this.
