Actually, given that the overwhelming majority of people _won't_ be running custom Android builds, it's also quite possible that Indian carriers are simply required to install whatever spyware the government requires, preferably without the knowledge of either manufacturers or Google. We're talking about a well-funded intelligence agency here, and you don't keep secrets by inviting unnecessary parties into the conspiracy, no matter how much you trust them or what "leverage" you have over them. Also, working with a global player like Google means Indian intelligence funds have effectively subsidized the development of tools that will in all likelihood be shopped to foreign spooks that spy on India. After all, it's not like they're going to get an exclusivity arrangement out of Google for this!
