I think this author is missing some key pieces. Kotlin was not developed by Google. It was made by JetBrains. Google decided to use it for Android development. JetBrains has been working on cross platform tooling for Kotlin from the start. This is nothing new. Although the article doesn't say this - it alludes to it - Google is not making competitive cross-platform products in-house.
