Feeling weird about Google

So Google is trying its best to get all GMail users to also use the integrated Google Talk IM service. I made very sure that I don't use it as the last thing I want to loose control over is IM logs. However, last night I logged into GMail and saw this:

Notice that the default is to "save chat history" which I equate to "allow Google to mine your chat logs and hand them over to anyone with a subpoena without telling you".

That's not evil? I suppose it's just a disingenuous business practice.
