The information does not need to be "open source", however you cannot put information in the Wiki that you do not have permission to use. That's where it can get a little bit fuzzy as far working out who owns what and what permissions we have.
For instance, we were given full permission to keep all of the Crossroads Tavern and Fords Keep when we left Wizards. However that doesn't necessarily mean we're allow to include extensive information about Greyhawk. Working out exactly what can and can't be put in for a setting where Wizards is actively marketing it (such as the Forgotten Realms) can be particularly tricky.
Likewise, for the Meeting Place we could include as much setting information that we want, but there could be other information that is owned by people such as D20 rules information or even information and stories about New York.
So, no setting would be completely copyright proof. The Rotunda would be the one most limited by Intellectual Property rules since it is set in Waterdeep, which is very obviously a hot property for Wizards.
