How come the German version supports English then? As far as I know the national language is still German so they shouldn't have the English version available.
There is no reasonable explanation for limiting access to languages in a game just because someone does not live in a certain part of the world in the first place.
This is especially the case if the versions are known to exist. All this policy does is forcing people to listen to bad voice acting even if people would prefer to listen to the game in the original language that Star Wars is associated with.
Fun fact, I had the exact same issue with Battlefront. So before purchasing Battlefront 2 I was promised again and again that it will be implemented later, until it was too late to even get a refund.
So as a summary, you are missing the point of the arguement, we do not ask for a "captain obvious" description as to what the policy states, most people want to hear reasoning behind the decision because from a marketing point of view, it makes no bloody sense whatsoever to limit something as basic as a game's language version.
PS
The "Origin store" version is forced on the user, so there isn't really a way to acquire another version aside from travelling abroad. Even if you try to go to the UK or USA store per browser, the moment you select a game you want to purchase, it directs you to the store of your region. Not that the prices differ that much.
