Net neutrality a key battleground in growing fight over encryption, activists say | Security - InfoWorld:
"ISPs might start to block encrypted traffic in order to maintain their business model. For example, if carriers can discriminate among applications, they can make some exempt from a user's data consumption cap. AT&T has already announced plans for such a service, called Sponsored Data, on its cellular data network. Among other things, this could allow content providers to cover the cost of delivering their data to consumers, making their content more attractive.
That concept may get more complicated if encryption comes into play, Meinrath said.
For example, in some developing countries, Facebook and mobile operators together are offering cheap mobile data deals that only cover Facebook. There are encrypted services that can tunnel through Facebook to give users access to other service, but carriers will want to know if anyone is circumventing the exclusive Facebook deal.
"The problem is that providers are going to say, 'We need to be able to know that you're not doing that, therefore we need to be able to ensure that you are not encrypting,'" he said." 'via Blog this'
