The text balloon is an excerpt from an entry on Google Blog - the official 'Google to the rest of the world' blog page. Could this mean that Google is concerned? Not for you, but for itself! Google has been till date undeniably the leader in Search and hence information management. "Information Management" translates to something like "We know what you did <insert yesterday/last summer...>"; of course Google has been working hard to project an image of upholding privacy of its users. While a certain independent organization thinks otherwise, and the same article also reasons "Why Not Microsoft". The entry on Google Blog, might sound sensible, if you consider Privacy Internationals own statement

"However we are aware that – in the words of the executives – "ad space is now the only game in town," and with Microsoft needing to play catch-up with Google there is a real threat that the organization could abandon privacy reforms in favor of ad revenue - or at least divert funds away from real protection and toward PR. The 2008 rankings will identify whether this fear will be realized."- Privacy International

The reasons why I believe Microsoft will not abuse the Yahoo buyout is because:
* Microsoft has been through enough lawsuits and anti-trust fillings.
* They have absolutely no experience in the "Online Business", and their earnings reviews makes this darn clear.
* Hence they will play watch-and-learn with Yahoo! (and hopefully Yahoo will cares <for you>!)

So imho, Google is either scared at the prospects of competing with Microsoft or they care too much for the people of planet earth (which will soon become an oven).

Edit: Some good (unbiased, really...) points here. 

Edit Again: I use Gmail & Google Services, in fact this domain uses Google Apps. Without doubt, Google Apps is a superior product.
