Some important context was missing from the blog post about FISA in particular. The NSA did not use FISA only to justify mass surveillance, but a broad interpretation of Section 215 of the USA Patriot Act was put forth to the FISA court as the basis for their action. As with many things, FISA itself is not the problem per se, but how it is implemented and interpreted.

Also, one must take the longer view with how data is used. Sure the current administration may be unlikely to abuse the data, but a future administration (like some past ones) may abuse the data if they have it. You might want to read up on J. Edgar Hoover.
