It's not "just" about the internet, or even IT - it's the revelation that we are forced into a panopticon, that all of us are spied upon.
Christianity has nothing real at it's base. It's just mythology. Yeah, there are a huge number of people who "believe" it.
In contrast IT shapes just about every damn aspect of our lives. Just about all financial transfers, personal communication, news, etc. etc. are stored on computers of some shape and travel the internet. The internet has enabled the arab spring, international scientific collaboration and many, many, MANY other things.
As a little example of the real impact the Snowden Leaks have, just look at the number of Christians[1] vs. the number of cellphone subscriptions[2]: There's about 2 billion Christians. And about 6 billion cellphone subscriptions. So please don't go yapping about how fucking important some half-dead fairytale is.

Addendum: Please also note, that the Pope doesn't even represent all Christians but just catholic Christians, of which there's even less than a billion.
Meanwhile, the Snowden Leaks are important to just about everyone. The only people who are unaffacted by this are people who live without any computers.
But hey, if you live with some indigenous tribe in the jungle, you're (probably) in the clear; Until realtime surveillance with satellites becomes cheap enough at least.
