As much as I'd like to be harsh on Google in this case, this is really more of an industry problem. If users want their data in the cloud, and accessible in the cloud without native local apps, that data has to live somewhere accessible. To you, to the company hosting it, and to the nice people with 3 letters on their jacket at the door.
