I'm really surprised that Google is moving towards a more integrated/proprietary/closed platform. Their advantage was always that they were able to make the chaos of the web sensible to navigate. As a trendsetter in terms of openness they were protecting their own best interests by influencing others to be open (and thus crawlable) as well. I guess Google has decided that the content stored in the walled gardens of other platforms (Facebook) has become so valuable that they must change their own approach in order to compete.
