When Google acquisitions go wrong: the disappointing story of Urchin
 

Of course, after buying the company, Google is free to do with it as they see fit. It's a shame, however, because Urchin's tools were indeed some of the best, and Google Analytics is not a drop-in replacement. We've long since given up hope of ever seeing 6.0, but given the fact that Google still offers a trial and still directs people to resellers for 5.7, perhaps we shouldn't give up hope just yet

Nasty. If Google makes a habit of this it is going to catch up with them and their stock price
