I think this is a near term threat for Software Freedom, and not one which many people are thinking about.
The threat is a return to mainframe computing. Giant server warehouses and very dumb clients with minimal local electronics which can be mass produced at minimal cost for the next billion.
In the demo they're running a game, but all the compute is happening in an Android VM in an Amazon warehouse. When you think about it, it's perfect disempowerment of the user, suitable for all kinds of unfreedom.https://www.youtube.com/embed/sG-eHDBu3h4android_in_cloud.jpg
