2. Barack Obama (BO) can "call for" many things, but after the latest elections he cannot do much. Even if he, personally and as a POTUS, would want to do something to protect NN.
3. If you hope GOP will do something about it... well, harsh reality is this: Republicans will do what corporate interest wants them to do. Democrats (along with BO) were doing the same. Now that GOP has the majority in both the congress and the senate they MIGHT pay lip service to the issue, but, nothing will change in essence.
4. Maybe you think/hope, people will go out on the streets, write petitions, fight for NN. If recent history teaches us something it's this: Snowden revelations didn't move much US citizens on to the streets. And, compared to NN, it was a larger issue.
(Hope for a better world is something to strive for, but after all these years, I've realized that there is only one reality: Interest. And Big Money has a lot of it to fight NN)
