That's right - he'll be telling us bullshit like listening in to millions of phone calls in France next or bugging Angela Merkel's cell phone. Oh wait.
Fear of spooks aside if you've got anything you don't want seen on the front page of the paper you don't trust it to a third party if only for the fear that they sell off the stuff with your data on it without wiping it first, or that they mix things up and another of their clients gets access to your data. Even places as big as Dell have had fuckups along those lines (when I was enquiring to buy a part I was sent the contact details of everyone else in my country that had also put in an order for that part). If it's not their own data their care factor is going to be close to zero - and MS have shown very clearly how little they care about their hosted email customers by the week+ long length of their help queue. If stuff happens to your hosted data you are just a tiny fish in a big azure ocean and they do not care (the tiny fish in the email example had a mere twenty thousand email accounts - not worth the time of MS to look at it in less than a week).
It's best to assume that if you put your data on any machine you don't actually own that the real owners may end up redistributing it in some way. There are so many ways it can leak in even well run places - backup tapes mislaid, asset seizure in legal disputes, theft, law enforcement hitting an entire datacentre instead of a VM belonging to their suspect, and now possibly corrupt spooks watching the stuff going in or out.
