In many cases you don't want the traffic to be encrypted, so you can audit what's happening. This is common in corporate environments (banks, etc.) It's good to know what e.g. stock traders are talking about so you can monitor for insider trading and market manipulation.

If they use the encrypted Googleprotocol using the Googlebrowser to connect to the Googleweb, you can't do that.

I get that it's important for Google to encrypt what happens between their browser and their servers, but the rest of the world has different requirements.
