Steam also does this. Most games are significantly cheaper in low-income countries like mine because otherwise they wouldn't make a dime here.

That's because you usually pay via credit card (or some other financial mean) which is cumbersome (and may be illegal) to spoof. But yeah, it can be hard to justify a subscription when it's the price of a full meal. Especially when other essential subscriptions (electricity, water, internet, cell services,...) is straining your monthly budget.

Steam is not the one doing that. Publishers decide regional pricing.
