Google deployed SPDY on Google sites when only Chrome supports it. YouTube deployed streaming with QUIC when only Chrome supports it. I'm not saying Google sites are sabotaging other browsers, just that these are examples of Google sites the work best in Chrome because Google teams can work closely together.
Google Hangouts uses WebRTC and NaCl without plugins in Chrome, but requires an NPAPI plugin or ActiveX Control (confusingly called the "Google Talk Plugin") in other browsers. Support for any browser other than Chrome is not listed on the Hangouts home page. You must search their KB to find the plugin installer.
