"Leverage" doesn't always equate to profit (or even revenue). The "goal" of the NSA is not profit, but mass surveillance. Whereas surveillance historically has been centralized, with the onslaught of mobile devices, we now have prevalent distributed surveillance (and perhaps more so than surveillance).

All the data everyone is feeding into FB/G+/Twitter/etc about their friends and acquaintances could not have been collected on such a mass scale by the NSA alone.

If you're a privacy conscious individual, there's definitely reasons to be fearful of this approach to surveillance by any governmental intelligence agency.
