The reason this is interesting is not so much that some companies have apparently provided backdoors so that governments can spy on their users. We already knew (or could reasonably surmise) that that was happening.

No, the fun part is that one government's spies (India's) have apparently used these backdoors to spy on the agents of another country (the US). So, you see, by mandating these sorts of security compromises, governments have in fact made it easier for foreign governments to steal their own secrets—an irony apparently lost on the author of the Indian memo and on the authors of these policies.
