I understand what you're saying completely. But my counter point would be, "How many people store documents with names like 'Embezzled money from the Cayman Islands.xls'"? Or, for that matter, "Super embarrassing or identifying medical diagnosis.pdf"?
The content of these documents and files is not being leaked. The term someone is searching for documents with might be. So, I may search for "2012 Taxes.pdf" (which is a real document title on my personal laptop) exposes nothing except the fact that I have filed tax forms. It exposes no more data than "2012 Disability forms.pdf".
To the point that I've stopped listening to RMS, it's not because of rabid anti-RMS Internet trolls. I used to read his rants and raves first hand. And while I agree with the philosophy that Information should be free, I also find room for things like copyright (when exercised in sane measures). I firmly believe there is more than enough room in the world for GPLvX, BSD, MIT, CDDL licenses, as well as any other license type. I choose GPLv2 most of the time, because that's where I stand. But my employer may not always choose GPL because there are things we write that give us advantage over competitors. And I'm a capitalist-ish. :)
RMS' statements started slipping from "Freedom for all" to "Conspiracy against freedom" a long time ago, and I just don't have the time or desire to get wrapped up in that nonsense. I respect what he does, but he methods and ideology need to catch up to the times.
