The actual spying isn't the biggest issue I have with the NSA (and GCHQ and ASIO and the others), the biggest issue is the way that these agencies are doing things that deliberately weaken computer security in the name of making it easier to spy on people.
Things like backdoors in who knows what software. Or pressuring software vendors under the table not to fix things that the NSA is using to spy. Or their various proposals for "key escrow" over the years. Or the potential compromise of security related algorithms and protocols (dual-ec-drbg for example is suspect and going back there were questions when the key-length of DES was made shorter by the NSA)
And lets not forget the cryptographic export controls (which still exist and can still be an impediment even if they have been wound back a bit) and what the government did to Zimmerman over PGP.
