A for-profit school has an obligation to its shareholders to maximize profits. If it can make more profits by providing an inferior product at inflated prices, and convince consumers it buy it - then it basically has to do that, or they are defrauding their shareholders. Otherwise the shareholders should pull there money and invest it elsewhere.
Private schools, by contrast, have an obligation to remain solvent, but also a broader mission to educate people, promote learning, make the world a better place and so on.
The word "privatization" in this context implies BIA is pursuing the for-profit model. By contrast a charter school in the US, or religious school, may be either for-profit or private and not-for-profit.
