It is not quite so simple
- wikipedia articles: clearly each on its own a creative work covered by
copyright. Distribution licence not compatible with the ODbL, but that
is not of any consequence for OSM since nobody (I hope) is proposing to
include Wikipedia articles in OSM. @Eugene a DCMA notice against 3rd
party text in a wikipedia article would make sense and I suspect that
the WMF would and has honoured such.
- individual facts extracted from wikipedia articles. From a WMF pov
unproblematic since "facts can't be copyrighted", from an OSM pov
problematic because they might have originally been extracted from a 3rd
party source and might be from a database rights pov, a substantial
extract of that source (for example POI data from google) if included
wholesale in OSM.
- wikidata data: the WMF claims no database rights in the collection of
individual facts and the reasoning for CC0 is based on the "facts can't
be copyrighted" doctrine. In other words, we could wholesale import
wikidata in to OSM from a WMF pov, however as already said, the
provenance of the data is unclear and has the same issues as facts
extracted from wikipedia articles. @Eugene I doubt if the WMF was
actually thinking of DCMA requests against wikidata content in the
published policy, as following one would damage their stance on facts
not being copyrightable. In any case it is clear that they have not been
policing their sources as SomeoneElse points outs.
I should point out that part of the differences in the WMF and OSM
stance is due to differences in the business models. The WMF, together
with google, are the main (if not sole) distributors of W* content and
at least the WMF clearly takes the stance that it is domiciled in the US
and that is the only thing it cares about (that is the polite version).
OSM on the other hand distributes its data to third parties all over the
world for further use and to be useful the dataset needs to be free from
rights of third parties that would limit its use in at least all regions
we consider important.
Disclaimer: I speak neither for the OSMF nor the WMF, nor does the above
touch on the ethical aspects of copying from a third party, potentially
a competitor, without explicit permission and potentially in violation
