So if the Foundation isn't interested in suing
them to enforce it, then
we're not left with anything that can be sued against. The *community* is hardly
likely to instigate a lawsuit against
Answers.com for what... breach of
contract maybe?
What would the Foundation sue for? The foundation doesn't own the
copyright. Only the authors can sue, and I expect they could in this
case:
Answers.com doesn't seem to be following the license.
In practice, however, I expect the only times anyone would sue for not
following the GFDL is either if they really didn't like the person
doing it (or what they were doing with it) and it was just a way to
stop them, or if they had modified the content and not released their
modifications under a free license and someone had a problem with that
on ideological grounds (or, they simply liked the modifications and
wanted to use them). No one is likely to sue for simple copying, but
that doesn't make it any more legal.
