Google News hiding other social share buttons

Today I’ve noticed that on Google news, the +1 button is shown as default.

But it only shows you other social shares when you expand a post.

Needless to say, Google News is a Google product, so they can do what they like to it. But users who have no idea what +1 is may miss out on sharing. It’d be nice to see the other icons as default.
