your point is taken, but I fail to see how this is a problem. Netflix is one service and is able to successfully serve content globally based on where they have the rights to that content. Disney can easily do the same.
Netflix owns ( or partially owns) the vast majority of original content on their service, the stuff they do not, some is licensed globally, some for certain countries.
For example, WWE Raw is licensed globally, but the WWE catalog content is in almost every country on Netflix, but here in the states, it is on Peacock.
I would think the bigger issue is that the content is presently licensed to Hulu and not Disney+.
A few examples, the Handmaid's Tale is owned by MGM, Hulu is licensed to show it here, but in the UK, it is on Amazon Prime.
Even content Disney owns, like FX shows, while on Hulu and Disney+ here, it is licensed to Sky Go in the UK, cannot be on Disney+ there.
Doctor Who is on Disney+ here, BBC in the UK.
