If you look at some of the considerations, it makes a bit more sense. It's not about the technical aspects of distribution. I don't know if it's ever been about that, especially in the last 20-40 years. It's about timing, marketing, legal issues, ect. You can't release a movie if the content is outlawed. A tiny difference in marketing can translate into millions of dollars. These things aren't necessarily "deal breakers" for a global release, but it's virtually (or maybe completely) impossible to do optimally in every region.
