I mean, Germans know exactly what happens when surveillance gets out of control - the Wikipedia page about the Stasi [1] is pretty good, including lines such as "counting part-time informers, the Stasi had one informer per 6.5 people" and "As the GDR began to fall, the Stasi did as well. They began to destroy the extensive files that they had kept, both by hand and with the use of shredders. When these activities became known, a protest erupted in front of the Stasi headquarters". Can anyone imagine US citizens storming the NSA, or the FBI? Even today those files are being reassembled, because people wants to know what happened.
And yet, what happened during the conference [2]? Angela Merkel essentially stepping in defense of Obama. She could have said she didn't agree. She could have remained quiet. And yet she speaks (mildly, though) in his favor, even while by her own admission "the questions have not yet been satisfactorily addressed". That was disappointing.

Any and all change begins with thought, speech and action in individuals, then in groups. Some things took a LONG time, and consisted of many small things. Even "reading and talking about an article about something that matters instead of watching cats on youtube or discussing font sizes" can help, IMHO. Unless you think it distracts you from doing something that would have even more impact, I don't see the problem? I get impatience, but not futility.
Since I'm living in Münster, where a lot of the German Pirates are and know quite a few of them, I'll be the first one to join any protest or demonstration they organize locally.
And as far as making the world a better place goes, I'm currently looking into the possibility of automated vertical farming with hydro- or aquaponics. Even if I just have a teensy bit of success with that it would probably have a larger impact than organizing protests, an activity about which I know NOTHING.
