Mathanxiety, what do you think is going on at Guantanamo Bay at this very minute? Do you think all those inmates have been told anything about why they are there, what their crimes are, etc? Sure, there are some bad people there - and some completely innocent people who they cannot tie to ANY terrorist activity.
Securing a mortgages is not the benefit of a web footprint, what are you talking about? It's the benefit of having consistent employment & banking records! I choose to turn those over to the bank, they evaluate & then grant me a mortgage which I pay for by way of interest. People who object to spying are not saying: let's live off the grid. That's a false dichotomy.
Like I said before, there are certain bits of information that we make public because without them being part of the public domain, things fall apart. This full-scale spying operation does not qualify!
