It’s unclear to me if this policy applies only to files that you’re hosting with their cloud service - in which case I think (?) the scanning of those files is no different from any other cloud file hosting service, which I assume also scan files to make sure you aren’t hosting something egregiously illegal.
Of course, this problem doesn’t exist at all if you just sell offline desktop software, but alas, the monthly SAAS business model has eaten everything else.
IALAL, but the content from the Adobe clarification posted earlier tells it applies to all files created with their software, regardless of whether you host them in the cloud or on your own computer.
Software like these should have no right to demand internet access. Subscriptions for using software that resides fully on your computer is such a huge scam
