From the context, what I gather was meant by the idea of "multiple Indias" was the socioeconomic status of different demographics in India and their app usage. The presence of specific apps gives a tell to which demographic they belong to.

In other words, the richest demographic used certain apps and was equated to folks in Mexico, followed by the less rich equated to folks in Indonesia and the poor to Sub-Saharan Africa.
