My question has nothing to do with the OS or other technical matters: what happens to a customer's original files if they knowingly or through simple ignorance violate Adobe terms of service?
Recently a naive friend of mine shared a horrific account of what can go wrong. Upon the birth of her first child, she had opened a Facebook account for her infant, using the platform as a repository for all the photos and videos she had taken of her infant. From her perspective, it functioned as a single place where she could keep them so that "when he grows up he will have memories"; she also used it to share the photos and videos with select others. The child is now three. Facebook recently informed her, via a form email, that they were going to delete the account because she had violated their terms of service, which states you cannot open a Facebook account on behalf of somebody who is under 13. As Facebook put it, "As a result, this account has been scheduled for permanent deletion. This decision is final and can't be appealed." Because she had no backups, she lost all of the photos and videos she had of her firstborn's first three years (it's not clear to me why she was unable to download them before they were deleted).
Adobe's service will have many millions of users. As sure as the sun comes up tomorrow, some of them will violate the terms of service, whether through ignorance, naïveté, stupidity, foolishness, maliciousness, or even plain misfortune. Will their files consequently be permanently deleted when Adobe detects their violation? I suspect (but am not certain) that Adobe is currently legally within their rights to simply wipe the user's files, as Facebook did to my friend's files.
Yikes.
