Absolutely, but those are secondary markets for most American businesses because there are an abundance of issues with delivering any application to those areas. Whether its political, cultural, financial, etc. Priority for most businesses and website owners is to serve the people you know you can serve first, then work on supporting those other areas.
Twitter, like most companies, exists to make money. If you're busy shaving off every bit you can from your requests, you're spending a lot of money. You're also losing money because I'd expect you wouldn't be serving ads, etc. as well.
Most blogs that exist to make money aren't targeting those without good internet either, so I don't really see the problem.

This isn't just about Twitter, its about making sure if you are helping build a local Mom & Pop Shop's online presence - which is where all business is now days - then you build it in a way that their customers might care about.
There is a world outside of cities, and a lot of people live there. The tech world needs to wake up to that, because those people where Ubers don't go, GrubHub doesn't deliver, they exist (and vote) too.
They vote, yes, but do they buy? Do they significantly contribute to a company's economy (even potentially)?
If they do, companies will be happy to spend time and resources in serving lighter versions of their content. But if they don't, there's no reason, from the POV of a company, to employ resources in something that doesn't generate revenue.
