Having a statement in Wikidata with a reference, where the referenced work is not published under CC-0, is entirely fine in my understanding.
When taking into account a single statement, then I agree it's fine.
Problems might arise when "a substantial part" of a given database is extracted and transferred to an other database. Let's recall that whether this transfer is done by automation or crowdsourcing doesn't matter, it's the quantity of transferred data, not the method used to achieve it that is covered by law (with some various scope depending on legislation, of course).
As a comparison: Wikipedia has plenty of references, where the referenced work is not published under CC-BY-SA or a compatible license. That is also fine. Or do you consider that a problem too?
If Wikipedia was transferring substantial parts of every work it is referencing, yes that would put Wikipedia in the same concerning situation. But it's not what is done in Wikipedia. Wikipedia and the references it uses have nothing close to a bijective or injective relationship: with the sum of data about a work gathered on Wikipedia you would not be able to build a work close to even a substantial part of the referenced works. On the contrary Wikidata, when it import large (sub)set of a data bank will allow to rebuild something very similar with, if not indistinguishable from, the original parts extracted.
As a concrete example, extracting all data from infoboxes of Wikipedia is done because it should enable to reproduce the exact same set of infoboxes. On the other hand this set of Wikipedia infoboxes where not created from a single source nor a set of sources whose substantial parts can be reproduced based on the data they gather.
