I'm a bit curious. I was under the impression that changing your site to show different content to "Google" than "regular users" was against TOS and could get you banned from results all together. Do big companies pay to get around these restrictions or have there been rule changes in Google Search?

Google is OK with it as long as you show the same content to a user going through Search as you do to the bot. They don't care if you show different things to users coming through other sources or directly hitting the URL.
