Palavras do Richard Stallman sobre o assunto:
"One important dimension of copyright is its duration, which is now
typically on the order of a century. Reducing the monopoly on copying to
ten years, starting from the date when a work is published, would be a
good first step. Another aspect of copyright, which covers the making of
derivative works, could continue for a longer period. (...)
Why ten years? Because that is a safe proposal; we can be confident on
practical grounds that this reduction would have little impact on the
overall viability of publishing today. In most media and genres,
successful works are very profitable in just a few years, and even
successful works are usually out of print well before ten. Even for
reference works, whose useful life may be many decades, ten-year
copyright should suffice: updated editions are issued regularly, and
many readers will buy the copyrighted current edition rather than copy a
ten-year-old public domain version.
Ten years may still be longer than necessary; once things settle down,
we could try a further reduction to tune the system. At a panel on
copyright at a literary convention, where I proposed the ten-year term,
a noted fantasy author sitting beside me objected vehemently, saying
that anything beyond five years was intolerable."
