I sympathize with this. On the other hand, you have to consider the big picture: - the open-source argument was mostly meant for everyone to look at the sources and draw their conclusions regarding privacy and security - these guarantees are mostly client-side (and you can't check what's running on the server anyway, even with the code) It's fair to say that the server code was proprietary for one year. Most of their code was still open-source during that time, and most of it (now that they push to the server repo as well) is now. I feel they would have taken less flak over this if their server code had never been open-source to begin with, or if they just released it now.
