For one thing, Adobe reader will scan your Windows computer for documents and upload all the titles and authors to Adobe's servers. I don't know if they also upload content by now, but I would guess they probably just fingerprint it, not upload the whole thing. So yeah, Adobe isn't your friend. Of course neither is Apple (you know how obsessed HN seems to be with Apple)
