Before Google+ came along, Google had many great products and embraced the OpenWeb. Now Google has abandoned Open Standards like RSS and CalDAV, and I think Google is more interested in building their own walled garden.
Bingo. It's very unfortunate too, as Google were uniquely positioned to be great defenders of the Open Web. Who else has the clout to do it now, as well as the motivation? Does anybody see Marissa moving Yahoo that way? I'm guessing "no" but would love to be proven wrong. It won't be Microsoft, you can bet on that. Red Hat are a moderately powerful company, but they aren't that big and could wind up acquired by Oracl…
Apple isn't perfect and is not an exemplar of a libre philosophy. Their most strategic stuff is pretty much all closed. But they have embraced a lot more openness than people give them credit. With Google moving everything into their own APIs it might not be long before Apple is more open than Google.
Apparently Google's even made their own proprietary zigbee competitor for Android@home. Whyyyyyyyyy.
