This is certain. For different countries there should be different prices. Since a person will prefer a pirated film than pay a large price for it.
If I am not mistaken they also said this before that they will make prices regarding the region in which people are living. But that is nearly a standard these days. In Europe you pay often much more for stuff then in the USA.
But you cannot make it cheap because other countries would buy the account with VPN or so to get the lower price. Other platforms has done this too, iam sure there is a good way to stir around this.
I think other platforms try to avoid the VPN problematic through linking your account to specific regions. I am not sure about this, but there are differences on other services fees in different regions, which would make sense.
