Physical items have ownership. If you store an item to a safety deposit box you are still owner of the item. Data in general do not have ownership (there are some special cases like copyrightable data or personal data, where exclusive rights equivalent to ownership exist). So anyone who have lawful access to data can use them (unless there is some contractual restriction). So if you upload some general data to the cloud, your and cloud provider's relationship to the data is the same.
