I think this should be amended to "don't do creepy stuff" in the cloud.

This is why encryption on our phones is so important. I want my phone knowing all sorts of "creepy" things about me (medical records, etc) so that it can be more useful. What I don't want is that information anywhere except under my immediate control.

Storing encrypted in the cloud is OK as well, I suppose, as long as the encryption key is only available to me.
