Only a very small fraction of Indians care or are aware about privacy. Even if there was no Jio, you wouldn't still have privacy. American/Chinese government and businesses already have access to your data. To think that governments will voluntarily abandon control over data is wishful. That ship has already sailed. I would rather give my data to Indian government and companies than foreign.

Also, you are really underemphasising the role of Jio in the digital revolution in India. If you live in India, you would remember the exorbitant data charges by telecom companies in the pre-Jio era. At least because of Jio, internet has more become accessible to the masses.
