And how do you think you lost control of your data in the first place?

Free software would never have deleted your files without asking you. Or maybe once before it would be fixed as a critical defect in a matter of hours.

I'm agreeing with you. However, when you move your data into the cloud, even if the software is supposedly free, you have no ability to verify that. You also don't control when or how that critical defect is fixed.

One little detail: I've read the official page for the Apple Music Subscription, and nowhere do they tell you they move your content to the cloud.

This app is not supposed to move anything. Just copy it. The deletion part of "moving" is a fraud, and possibly illegal.
