Clearly part of addressing mass surveillance would be to get changes at the NSA, but they are not the ones we need to make listen. Politicians are. US politicians who support and fund the NSA or doesn't voice their opposition. Politicians all over the world who allow their own surveillance organizations to be complicit, or who are not putting enough pressure on the US government to make it a foreign policy problem instead of merely a small nuisance.
And the large parts of the public who are not yet aware, or not aware enough to care.
The NSA is at the very end of a very long list of targets, each one of which may help put pressure on and/or have some power over the next target on the list.
