To a non-black person, particularly a Civil Libertarian, it may seem odd that roughly zero black people seem to care about this issue. The people who care are almost entirely whites who make fairly good livings. Slate, for example, is still dominated by Snowden-related news. To those folks these various Snowden-revealed programs are very troubling, and possibly indicate our liberties are being wantonly violated.
Blacks, OTOH, who generally a) have had their liberties wantonly violated by at least one level of the government, or b) had a recent (like a grandparent) whose liberties were wantonly violated just don't seem to care that much. There are no Snowden-related headlines on the Root. Black poll numbers show less black outrage. It just doesn't seem to be a big deal to them.
The reason for this is pretty simple: Blacks have had their rights wantonly violated. And it was nothing like the NSA/PRISM/etc. stuff that's coming out.
There are a couple reasons for that.
1) Historically privacy rights are simply the last thing a black person has to worry about. The KKK did not assemble a massive file on the black people living in the Black Belt, and then use the data to pick the most lynchable black guy. They didn't need anything like that, because the Black Belt is almost entirely rural. They just had to ask the Town Gossip who was kissing a white girl. They would consider that rape. If nobody was doing that (or the gossip[ hadn't picked up on that) they'd kill pretty much at random.
2) In general blacks worry about small institutions more then big ones. If cafes are discriminating against blacks the NAACP knows exactly how to bully the CEO of Starbuck's into stopping it. They know how to make sure he follows through. They have the resources to get this done. It's easy.
OTOH they do not have the resources to convince 1,000 mom and pop coffee stores to do the same. In more recent examples, several academics have concluded the reason that black unemployment is not rebounding since the end of the recession is probably that nobody networks with black people. How the fuck do you fix that? A magical genie who can a) convince white people to make a point of networking with qualified blacks, or b) magically transform millions of black people into good networkers? Damned if I know. I'm positive you can't do it on the NAACP's budget.
This is magnified when you're talking about the government. The President and Five Supreme Court Justices can solve any racial problem black people have. Therefore groups like the NAACP and Urban League focus like lasers on getting the expertise necessary to get those six people to act. They have lawyers who know the Federal Courts. They have relationships with leaders in both parties. They know how to bully politicians at the Federal level.
