>Apple are re-distributing.

Only to the user they got the audio themselves. Any proof they're redistributing random X users not tagged in their collection files to others?

In any case, the whole "piracy" angle is BS (not to mention it lacks intent and profit from explicit piracy).

What's at stake is plain bad program behavior -- deleting users files without explicit confirmation, making bad matches to different versions of songs, etc.

>How do you know that?

I'm smart like that. Or rather I have read in detail about how Apple Music works. Besides, the burden of proof is on those making that claim.

>That you are the sole owner of the rights of a piece of music does not grant Apple an automatic license to distribute it "just to you".

I call BS. That's exactly the same as Dropbox/Google Drive whatever making a copy of your files and distributing them just to you, and tons of other Cloud services handling your files besides.

At the moment you use Apple Music (which is a services for moving your music collection to the Cloud among other things) you are implicitly allowing Apple to upload and serve you your music files. Plus, you explicitly approved the whole process and granted that right when you clicked on the iTunes/Apple Music license agreement. Nothing different than what happens with thousands of other services.

The work was not merely backed up, but repackaged into a format that Apple is more comfortable selling in; .wav files were converted to AACs, and rare remixes were converted to the popular hit versions. The old stuff was then deleted from local storage without permission, which is intent to make these privately owned tracks an excludable good, not to mention theft.

A further problem arises when a user has a non-transferrable IP that Apple doesn't sell in his left pocket and some generic track that Apple sells in his right pocket, and Apple picks both pockets with the intention of becoming a redistributor. The user does not have permission to transfer, nor has he indicated to Apple that he's given permission, for Apple to acquire the proprietary IP and redistribute it. It is entirely plausible that this proprietary IP was never intended for sale, was a trade secret, was a nude tape, or was a classified recording.

There's all sorts of issues with Borg-style cloud IP assimilation under the "Fair Use Doctrine", and commercial usage of the IP for "backup" while simultaneously being a vendor of the IP (and competing products) make it unlikely that you could apply fair use credibly for something this expansive.
