Each country builds and maintains its own infrastructure for connecting citizens to the wider internet. The decision to expand and maintain the infrastructure in one region and not another is up to those in power. And therein lies the problem: Ethnic and religious minorities who are excluded from their country's political process may also be systematically excluded from the global internet.
Advocacy of individual economic freedom is often criticized because, among the many possible exercises of that freedom, is radical capitalism: the single-minded pursuit of profits over all other social concerns. Yet, a dedication to monetary profit alone in such conditions as described in the linked study would be preferable to the actual circumstance: a dedication to denying an oppressed group a vital service. Certainly there is much to be made by selling these groups internet service and someone is forgoing profits by not making those sales. More accurately, someone is compelled by government to forgo profits.
If all you want to do is make big profits, by definition you do not want to limit those profits by declining sales to politically unpopular groups.
The economist Milton Friedman said, "Human freedom and economic freedom work together." I disagree because that understates the connectedness of those freedoms; the two are one-in-the-same.
