Hello everybody,
There is a phabricator ticket on Solve legal uncertainty of Wikidata https://phabricator.wikimedia.org/T193728 that you might be interested to look at and participate in.
As Denny suggested in the ticket to give it more visibility through the discussion on the Wikidata chat https://www.wikidata.org/wiki/Wikidata:Project_chat#Importing_datasets_under_incompatible_licenses, I thought it was interesting to highlight it a bit more.
Cheers
