Electricity is a basic commodity, it has no real unique characteristics. Just 230V +/- 10%, 50Hz, (mostly) sine wave here in Europe.
My data is unique which is why it is so much more valuable. Do I trust others to look after it? No!
Sure, I might use a cloud provider to store an encrypted backup, but then if they bugger me around I still have the original, and they don't have access to whore me from advertiser (or TLA) to advertiser. Going cloudy might suit small businesses that have no tech support and limited requirements (say just email & dropbox share) but if you have big demands the cost of the "cloud", and the bandwidth needed to work with, it becomes uneconomical even before we get to data sovereignty.
