If they raise the prices in those countries they would make less money because volume of subscribers would go down enough for total income to decrease.
If they lowered the price in the US, they would make less money because the subscribers they would gain would not be enough to offset the reduced income from each.
That’s it, it has nothing to do with operating costs or fairness, it’s just a question of what price point they believe will make them the most money in a given market.
In small (population-wise) rural areas like that, where positions are running uncontested or only contested in the primary, it’s actually possible individuals could make a difference. But there’s some caveats.
If the area is extremely Republican and would never vote for a Democrat, don’t run as one. Unlike in races like President and Senate, independent and third party are actual choices at this level, they’re not simply false choices.
An individual could find some local issue that matters to a lot of people in the area but seems to be being ignored. Talk to neighbors, local people, etc, figure out what they’re upset about that actually falls under the purview of local or state government, then make that the core of your platform.
As long as you’re not officially listed as a Democrat, you’re not platforming on things that the locals would never vote for (and you probably couldn’t do anything about anyway in the lower office you’re running for) and you’ve actually done some local research and found an issue that a significant number of people in your area are upset about, you actually have a chance. You’d probably lose, but there’s a real chance.
