Well the problem somewhat lies in the archaic Communications Storage Act of 1986. I had a custody battle and did a lot of research about it, wanting to use some Facebook evidence. Basically, it's worded as to give direction as to early/mid 1990's message boards. I suppose the law never imagined anything like the current internet collecting information as it has. The many different ways information could be stored extends far beyond old BBS channels.
To an extent, there still is some protection of your privacy due to the DCS. But there is a huge gray area for other people (not companies) to exploit. I'll admit my skepticism against 'big brother' and that if someone has the power to do something...'good morals' won't exactly apply to stop them, especially in positions of power such as government or law enforcement.
It will be a sad day when we lose the internet as we know it. Whether it become channeled like a television, or completely controlled. I believe there will be a digital revolution eventually. Just as the physical revolutions in Egypt, Libya, Syria, and the US back in the 1700's. Right now they are starting to abuse their power. And as that escalates, I imagine people will start protecting themselves more. It's why I have no problem educating people on privacy, encryption, and just general habits to avert social engineering.
This is a very, very informative PDF if you have the interest and the time.
The SCA can be powerful, in both the right and wrong ways, unfortunately.
