This article is just someone’s frustrated rant, poorly written.

Definition of OOP has changed over the years, early on it was a lot of focus on inheritance & polymorphism, but today it is mostly about composition, which is basically what you do in FP as well.

New inventive ideas like Go's & Typescript's interfaces flips the relationship between the caller & the callee. Or Rust's traits where you can expand your existing types with new behavior.

There is criticism about OOP to be said, but using Java as your strawman to invalidate OOP is not really a good argument, it is just one implementation of many.

Edit: removed the word dynamically from description about Rust traits.
