The irony of trying to block content/visitors based on country, while publishing on a platform called the "World Wide" web. IP address blocks that roughly correspond with geographic regions is kind of a design flaw.

That's what happens when you have idealistic nerds implementing a vision of what they want , rather than the typical software that is designed and built almost like an representation of the organization that built it, i.e Conway's Law.

Is it a design or implementation flaw?

There's no irony. A given name does not constitute a mandate to use it any particular way.
