My understanding of contract law is that it requires an offer, acceptance,
and consideration.  It seems legacy users accepted an offer of an
assignment of IP space, but for those who got it for free I don't see
evidence of consideration.

For legacy's that got their assignment for free, what would their claim be
based on if not contract law?
