I think you're confusing language openness with freedom of choice for consumption.
I think you're confusing deduction with speculation. I'm fully aware of the difference between language openness and "freedom of choice for consumption". I just don't agree with the wisdom in tying my workflow to a company like Jetbrains.
why?
What is wrong with jetbrains, and also what is the connection between then and a free software(kotlin)
also, vs code is by microsoft. Any time microsoft can say that plugins needs to be review by them. also vscode is ahead is a very hard option?
Are you upset for the election in USA?

Inside company <30 people working on kotlin that give us more than 100 people outside JetBrains involved in Kotlin development.
Once Jetbrains no longer controls Kotlin's future and most Kotlin users are not Jetbrains customers, then I'd consider it truly open.
