I have exactly the same sentiment. One of my big fears about Google is that, similar to what happened with Java and Sun, they will ride on their easy money to make cool things and then one day when / if ad revenue dies off (or hell, even just stops growing) it will all go away or get sold to hostile competitors.

In this light, seeing Google actively driving commercial sense into their services and cancelling those that will never fly is, while disappointing, also reassuring.
