Um, this is how software was built in the olden days. C++ literally began as "we could write a preprocessor to automate the tricks everyone uses to implement polymorphism in C" (CFront). And prior to that, the same tricks were used in assembly language programming. So this article has recreated the history of OOP, which was to create tooling to better support programming techniques already widely used. It wasn't some religion invented by the priests and sent forth on tablets, although due to humans loving them some cult, it became that eventually.
