If I'm reading it correctly, it looks like the comparison table says Knowledge Graph has an order of magnitude more data than Freebase did?

What's the issue with Wikidata's license? Both Freebase and Wikidata seem to be Creative Commons licensed. Is there a catch?

As for progress, if there's anything slowing the migration of Freebase data into Wikidata, I would guess it's Wikidata's different citation standards.

Given that the original Freebase data is still available, would it be correct to say the issue is Google isn't releasing their new data for free?
