Benjamin, all,
taking from the beginning a license like ODBL would make it hard or
even impossible to switch later to, e.g. CC-BY-SA 4.0, which might be
a more natural choice since the rest of the WMF projects are mostly
licensed under CC-BY-SA. ODBL and CC-BY-SA are not mutually
compatible.
The question of a license is complicated, has wide implications, and
deserves a much wider discussion in a community that does not exist
yet. Unlike any other license, CC-0 allows us to later change the
license. Also, CC-0 makes it easiest to include the content from
Wikidata in the Wikipedias and anywhere else, which is great for the
start.
CC-0 seems to me the only choice that would allow us to delegate the
proper discussion about the license into the future, when the
community is actually there. Any other license would make such a
discussion impossible.
I think such a discussion can be prepared now, and arguments can be
gathered for possible licenses, but it can not be decided now -- it is
simply too early.
Best regards,
Denny

From my
understanding, yes, it won't be possible to import data from
Wikipedia infoboxes etc. into a CC0 WikiData. (At least under European Union
law, where databases are protected by copyright)
The answer from Denny Vrandečić was: "Wikidata does not plan to extract
content out of Wikipedia at all."
The problem, I think is, that Wikipedieans just expect that this is exactly
what WikiData is actually meant for - to absorb the data stuff from
Wikipedia. And on the other hand: how useful is WikiData, if you tell the
Wikipedians, that they are not allowed to move data from Wikipedia into
WikiData?
This is the reason why I recommanded from the beginning to adopt for
WikiData not the "no-restriction at all" CC0 licence but one fitted to
data and respectfuil to Wikipedia's general choice of creating a
common good of knowledge by ensuring the need to share the reused
information (share-alike clause of CC-BY-SA) : the Open Database
Licence (ODbL) from the Open Knowledge Foundation does exactly this
and is already being used by ma,ny people,; including official cities
or regions for example here in France.
<http://opendatacommons.org/licenses/odbl/>
Unfortunately it looked back then like the decision was being taken
without any real debate when it should be at the center of the
project's grounds...
