Maybe that example was made terrible because the author couldn't think of a good ways to show how great this can be. I'm obviously a fan of SOLID, and OCP is exactly why I don't worry if I have only one class at the beginning. Because I know eventually requirements would change and I'd end up with more classes.

Some time ago I was asked by a less experienced coworker during a code review why I wrote a particularly complex piece of code instead just having a bunch of if statements. Eventually this piece got extended to do several other things, but because it was structured well, extending it was easy with minimum impact for the code-base. This is why design matters.

Above claims are based on nearly 2 decades of writing software, 3/4 of it in big companies with very complex requirements.
