You don't have to be upset to think that this is interesting! Indeed, it's a very different face of "data changes law enforcement" than the NSA story. Whereas NSA has a specific mandate, FBI can use anything seized for a broad variety of uses. This may always have been true, but the scope of the seizures has increased now that they can include entire server copies, which host many different services. It's a dramatic increase in prosecutorial power (which may or may not be a good thing, I'm not making a case either way). It's also not clear to me (maybe it is to others) where the limit on seizures is. In the extreme case, AWS is used for all kinds of criminal activities. Can FBI seize copies of AWS, and then with warrant go back and get evidence for other investigations? I doubt they would try, but somewhere between this extreme and the child porn server extreme is some sort of inflection point, both practically and legally.
