The military call it mission creep.The cloud does concern me greatly in general, which is why I refuse to use any cloud service for storing files.
There seems to be a long term push to get everyone to voluntarily put their info and data on public servers whether its facebook or a cloud backup service. At some point in the future, how easy would it be for a simple law to be passed in vague language that allows the government to essentially index all of this info and data to search on a whim without any evidence to back it up? We saw similar stuff in the US after 9/11 with the patriot act and at the end of 2011 with the NDAA. Take note each time some attack happens and which civil rights are eroded right after. It feels like its slowly creeping towards a complete police state and we seem to gladly accept it.
