I'm sure the data is used for various nefarious purposes
No doubt planned by a guy with a cat in his lap, who likes to say "eeexcellent" a lot.
That's a bit farfetched, but everything the NSA was confirmed to be doing was also farfetched before Snowden leaked those documents.
There was nothing far-fetched about the idea that the government was dong metadata analysis, or working with large corporations to access their data. Both of those things were pretty much an open "secret" well before Snowden leaked anything; he merely provided greater detail about the extent of those operations, and brought that information into the public consciousness.
Besides which, if your thought process goes along the lines of "these far-fetched things have happened, therefore all these other far-fetched things are probably true"
