Are you being sarcastic?

This strategy of getting start-ups to explain their business models and share their technologies...

This kind of accusation seems so childish. Of course Google can start a competing service, and looking into possible acquisitions instead seems like a sensible thing to do before starting one. But Google's goog411 has nothing to do with the Free411 business model - they aren't trying to sell ads, they are gathering speech data. If Free411 had an enormous database of voice samples, goog411 might have never been. Just because Google didn't consider Free411.com a valuable acquisition doesn't make them evil.
