You've already made a pretty big leap from surveillance to storing surveillance data persistently, and another to the tools. I'm not going to argue that mass surveillance is morally neutral.[1]

Tolkien's Palantirs let you see and communicate and influence across vast distances. That's no more immoral than a videophone. Of course, that's also not surveillance; that'd be a telescope. But surely telescopes aren't immoral?

[1] I mean, I would, but (1) you can't create a mass surveillance system from a morally neutral or positive place, and (2) it seems nearly impossible to implement a mass surveillance system without creating more harm than benefit. So it becomes a boring semantics argument as to whether mass surveillance is fundamentally immoral or not.
