It’s been ten years since the term open source was launched and one of the architects behind it, Bruce Perens, discussed this in an interview
“No. If Bruce Perens could change anything from that day in February 1998 when he announced the Open Source Definition and the Open Source Initiative he’d alter the very way open source licenses are ratified, to halt what he regards as the chief threat to the next ten years of open source: license proliferation.
Perens said the growth in licenses, especially the emergence of “badgeware”, or attribution licenses used by numerous open source companies, such as last year’s Common Public Attribution License (CPAL), is dangerous. Today, we have 68 licenses ranging from the well-known GNU General Public License (GPL) to the, well… the OCLC Research Public License 2.0 recognized by the OSI.”
