The worldwide statistics that have been showing in BearShare since 2001 say
the opposite. The "Freeloaders" have dwindled from 33% in the first few months
to a steady 13% for the past few years.

Also, don't forget that the "Browse" function (which I assume you are using to
guess whether people are sharing) only works between BearShare and
LimeWire. It can also be turned off, which a lot of the smarter users will do.
