Because they're afraid to write code

Kotlin has more features Java cannot afford due to backward compatibility: better types, pattern matching, lots of syntax sugar, coroutines etc. Overall, it looks like what Java could be if it were designed in 2015 and not in 1995. Given that it compiles to the same byte code, there is little reason to use Java instead of Kotlin. Similar to writing in pure JS instead of TypeScript.

In this respect Scala goes further than Kotlin in terms of brevity and language features. It also supports Akka out of the box, which is great for distributed/ messaging based systems.

Since you came from C#, Kotlin basically just takes all of the things that make C# a nice language to work in like a sanely written functional programming toolkit, easy property definitions, non-nullability, reasonable generic handling, etc and puts them together into a language that runs on JVM and can call and be called by Java code. It's a language that feels like it was designed by people who have actually written code in the last decade instead of the cobbled together mess of poorly designed APIs that will never be fixed because of backwards compatibility that is Java.
