it's paid propaganda (paid meaning tax credits and gatekept access to financing, distribution). hollywood movies exist for shareholder profit, making money for changes like this easily accepted and even incentivized. see also the changes they routinely make to meet complex rules around including enough british actors for lucrative british tax credits, and extrapolate more globally.
the defense against this in this thread can be summarized as "it doesn't matter" or "it's not that much" while it is what's happening
I don't mean to contradict you, your comment just made a good opening to post the world map from the movie. The map is really (really…) not detailed, and honestly I find it hard to identify the problem border in it off the coast of "Asia".
Somebody on Twitter pointed out the sea border around Greenland is controversial as well, something about fishing rights.
what hollywood does for US imperialism is also shameful and obfuscated. studios work closely with military and CIA and no it is not disclosed as propaganda.
