Uploading software and music on Dropbox, what to be aware of.

It's important to realize that any cloud (SaaS) provider is actively engaged in scanning your data.  There are multiple reasons for this, one being liability.  But the second, is government intelligence -- this happens more often than you might imagine.  To put it simply, without getting into the specific laws, the government can serve your company with a secret order that you must comply with, and you cannot disclose.  This grants them unfettered access to all your data, without your (the customer's) knowledge.  This happens in very big companies, some who promote security and privacy too, and I won't name them here.  As a smaller example, think about the various "VPN" services that promote the same, then we discover the FBI or some other agency has been tapping their data. 

If you need to store data into a cloud drive like Dropbox, you might be able to create encrypted containers, like with Cryptomator -- it's just extra steps (for now) that make it more cumbersome.   But suffice it to say, anything you post into any cloud presence is most certainly being analyzed for multiple purposes -- not just you specifically (well, you'd hope not), but for larger context.    This includes any cloud-based services such as virtual machines (think of the popular actors in this field).

Sorry that was so long, but I feel like many people don't realize this -- and I'm putting this here for posterity.
