creativity is to be shared but also protected because usually the artist wants credit for it. now if you are keeping things in "the cloud" (independend who is providing it to you, be it apple, google, adobe, ...) and you intend do work on them, you have to ultimately trust the owner of the clouds servers on your data staying your data. making a small website with holidays pictures is one thing but working with real data for high payed contracts i would never just put the data anywhere in a cloud... after all winds can carry clouds anywhere.
