I must admit that I find it hard to agree.  I do not see how the OS, or the Emacs version, or 
the combination of both could be used to identify you as a person.  But if the can't, why
would you consider this information private?  And even if it could, doesn't it pale beside
the information that is necessarily send to the archive (e.g. your IP, a partial list of
the packages you're using, etc.)?

I think that our desire as package maintainers to learn how and where their packages are
used is legitimate.  It helps us to direct our efforts and our time to those enviroments
that matter and to make informed choices about what degree of backwards compatibility we
should offer.  In the absence of any concrete risk, I tend to value our desire higher 
than the interest of users to keep data private that can only be used for anonymous usage 
statistics.

Now, I understand that I'm biased, and that your priorities may be fundamentally different
from mine.  But I believe that the availability of some halfway solid statistics would
improve our ability to make informed decisions about our packages.
