Diglossia and bilingualism is very, very common in the world and probably the norm for humans: large monolingual countries are exceptional. Even in monolingual situations, people invent different registers for different formal situations. There is no reason that different linguistic codes cannot coexist for different functions. This argument can easily be extended to the other national languages: Preserving a national language like Italian or French is all very well, but English is the language of international communication, science, and technology, and expending a child's language-acquisitive resources on a language which won't connect them to the rest of contemporary humanity seems like too high of a price. The reason some languages are "dying" is because colonial powers attempted to exterminate those people and their community, through a variety of uses of power. In the article, the colonists exterminated more than 90% of the population and sent the survivors to a concentration camp. Just horrible. There's no reason to pretend that this community's precarious cultural position occurred through ethically neutral events.
