Here is a meta-comment that may seem irrelevant but I truly wonder about this odd tick of internet writing.

The title should be "Kotlin Sucks" or "Why I think Kotlin Sucks". The article doesn't say anything about the circumstances that lead to the sucking (e.g. the main developer suffered a serious brain injury midway through the project) he just lists and details aspects of it that suck.

This incorrect, misleading use of the word "why" in the titles of internet articles is so common I must ask, "why?"
