oh yes indeed. an analogy would be if i were handed a sheet of
handwritten script and i photocopied it - i might be reproducing a
copyrighted poem/short story/haiku without ever knowing that it was

of course, it would be difficult to sue me, as i was not aware of the
infringement, but it would be easy to prevent me distributing any more
photocopies. and it wouldn't make the photocopies i had already
distributed "free" in any way.

also, because ODbL requires attribution which states that the original
data was ODbL licensed, it would be harder to claim that i didn't know
the database even exists.
