But you could prevent reuploads with per-user de-duplication, while avoiding the privacy issue of cross-user de-duplication. I could see why this would be more

  I have a hard time understanding this line of argument. Per-user deduplication will mean, I need not upload the same file twice into my own account? What's the use of this? I keep some of my 'paid for' software installables backed up in my Dropbox, and they tot up to ~1.5 GB (the Humble Indie Bundle games). When I started the upload however, it took maybe 5 seconds because of cross-user deduplication, and I am super grateful to them for this feature. I imagine this feature saves users tons of bandwidth, as most of the people I know use Dropbox for backing up important software, rare music and videos.

    > I have a hard time understanding this line of argument. It's not a line of argument. It's a line of inquiry. You've given anecdotal evidence that cross-user deduplication benefits you and people you know, but what about some actual numbers from Dropbox? Producing actual numbers -- "eg cross-user deduplication saves our users 30% of their upload time and bandwidth, on average" -- seems like a great way for Dropbox to counter this issue. > I imagine this feature saves users tons of bandwidth, as most of the people I know use Dropbox for backing up important software, rare music and videos. We don't have to imagine! Let there be numbers! Also -- "rare" music and videos that everyone's uploading duplicates of? ;)
