The key issue (at least for me) is whether they've tried to benefit from marketing user-specific data. I can't recall any such effort, but will gladly to defer to someone more knowledgable. I'm not sure specifically why their multiple ad and social network efforts have failed, but it might be because they haven't been willing to do just that. On a general note, I find it frustrating that a lot of the discussions around this area end up with people talking past each other. Some people are concerned about advertising, others about privacy, others about using user data, others about open source software/hardware, others about encryption. They've got some overlap when it comes to specific features, but often get conflated, making the discussion even more difficult. One thing I've appreciated about reading your comments is that you often are able to cut through that quite decisively. Thanks!
