Why add a layer of complexity to an already stable OS? PV & Team do participate here at LQ so feedback via the forum is great therefore sufficient enough. I personally don't care to have my system(s) reporting back to anyone. If Debian has that means then so be it. Another reason not to use Debian for me. Nanny, big brother or whatever you call it is just not the way to operate a OS functionality.
Some may feel trusting for their systems but why open or provide another possible security risk?
Folks, we can't have everything in a distribution but we do have the means to add whatever is needed with a little work on our part.
