It all comes down to privacy (Score 3, Insightful)

IANAL but speaking from a US centric view, any piece of information thats hosted on servers not within your personal control, is much more easily accessed by the government than documents on your own personal hard drives. The standard for personal search and seizure is much much higher than for a corporation. Recently lets take a look at Google and AT&T. Google handed over some personal information after mounting a defense, but they still handed it over. AT&T is just dumping all internet traffic to the government so get favorable treatment elsewhere. The more I hear the less like about these online services having so much personal info. I won't be using more than I absolutely need to.
