Well Samsung or LG being a Korean company, do not focus their product or services in South Korea? Bixby, Galaxy devices, Samsung Pay, even LG's OLED TV is available to US customers. Like it or hate it is your choice, but they never really hold up about which product or feature may be released for specific regions.
People outside US of A pay a heavy premium over what most Americans pay for their iPhones, yet receives less and less of Apple services. And don't forget many of them pay in cold hard cash.
An iPhone XS costs $999? Big deal! Come over to China or India, then convert the price to USD, yeah you'd be popping your eyes out.
For what it costs, Apple could've at least have a decency of providing them the services they deserve.
