It's all just another predictable move to push the legit organic serps down below the fold and off the page. Once again, subtly or not so subtly forcing people to pay the extortionate adwords rates if their business relies on search traffic.
It's clearly not just brand related. I just found these expanded sitelinks for a "city+newspaper" query.
It has nothing to do with improvement. People use a "search engine" to get a number of DIFFERENT sites. Once again, if people want to find something at Amazon, they go to Amazon.
"Push the organic results down" <--- googles new mantra
More to come, you can be sure of it.
