Which would be understandable if they ever shut down any cloud service offering of this level before (which they have not).

This whole "Google loves to shut stuff down" is really tired and overplayed.

Go ahead and compare Google's track record with Apple's or Microsoft's, or any other company. They are about on par, yet Google almost always gives 6+ months notice (often over a year), provides one-click alternatives, allows you to export your data in one of many formats, and more often than not has an in-house alternative that you can use automatically.

Take a look at the wiki page of google's products [1]. I'd be surprised if you even knew about 10% of those, let alone used more 1 or 2 significantly.
