Hulu recently blocked paying customers who are accessing the service internationally via VPN software. This seems like a particularly vindictive move, but, really, Hulu doesn't want to cut off their international customers. Someone forced them. No company says "we're making some money from overseas customers. Is there a way we can do less of that?" So it's pretty clear to me that this wasn't their idea. It wasn't their idea to geo-block international users in the first place.
So who wants Hulu to be far less useful to international customers? The same entertainment companies that have archaic distribution agreements for different world regions, and also refuse to pay much attention to those non-USA regions.

PPS - I mean no entertainment, ever, in any form. Zero exports. That's the win condition, apparently.
