> I'm confused what this really means. Countries don't store their really secret things in Azure. So what do we think the source of this surveillance was?

Why wouldn't countries store secret data in Azure, Google Cloud and AWS services? I think that this is quite common.

I think you're misunderstanding my question. I'm not saying "this story is bogus," but rather I'm saying that this sort of data is probably not the kind of data which is acquired through really secret means. Perhaps it was purchased from providers, or some other less-secret method.
