Where's the disagreement there? The court concluded that reverse engineering to gain access to the non-copyrightable elements the object code contained was legitimate. It didn't assert that decompiled code wasn't subject to copyright.

Decompiling code is a reverse engineering method that provides access to the non-copyrightable elements of the code.

[mjg59]

Yes. It also provides access to the copyrightable elements of the code. In this respect the decompiled code is identical to the object code, which is also made up of a mixture of copyrightable and non-copyrightable elements. Combining copyrightable and non-copyrightable elements into one thing gives you a work that copyright can be asserted over. The argument in the case you cited is that the defendant extracted the non-copyrightable elements and built their own work based on those. That's not what's happening in the case under discussion here, which is derived from the copyrightable elements as well.
