How about: Google shut-down a knowledge-base that was curated by a community, that provided regular data dumps, an online interface and an API - all with an open license (the original data source is nevertheless Wikipedia et al). Google's new venture is basically the same core technology and data but the crawler run also over the scrapped web content. And the only access for non-Googlers is via an API. Make your own conclusion from that.
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?
