So basically this requires an opt-in scheme instead of the opt-out that you
have in mind. Users are very sensitive when it comes to collecting
information that are perceived as personal. Based on that I think the value
might not be as big as you hoped. Currently the plan is to collect info
about the number of active users as part of the automatic update but not
much more. Similar to Tor I'm not so sure if I see the value in having a
huge collection of statistics that we are not planning to use. Besides the
obviously problem of privacy the bigger your data set the more work you
need to invest in processing the data.

Based on that it would help if you would provide some cases where having
such detailed statistics would help us improve LibreOffice.
