I think app stores across mobile OSes maintain region specific marketplaces. Developer accounts are also able to be localized. I assume it is trivial for, say, Google to block all apps from Chinese developers on the Play Store for any customer localized to India.

I believe most of this stuff is asking Google and Apple to remove the apps in questions from their Indian app stores.

So its just about the Indian Gov sending an email to Google and Apple. Didn't know its was this super easy once the country decides regardless of any knowledge about how this is actually done.

One of the many advantages of a centralised app store is just how easy you can support dictatorships and populist politicians ...
