Update license of D3DMetal for redistribution

CrossOvers and Whisky both redistribute D3DMetal in their app. We would like to do so as well but the included license does not make it clear. Please update the license to make the exception clear so we can distribute under the same terms as those apps.

FB24262864 is also filed regarding this issue.

We need the same clarification for Apara, a commercial Mac app that runs Windows games on Apple silicon. Direct3D 12 titles run well only through D3DMetal, and today every customer has to download the Game Porting Toolkit from Apple themselves because the licence doesn't make clear whether a commercial app may redistribute it. We'd welcome either an updated licence or a process for requesting permission, and will accept whatever conditions Apple sets (attribution, supported macOS versions, removal on request). We've filed our own Feedback referencing FB24262864.

the licence doesn't make clear whether a commercial app may redistribute it

The license clearly says, "distribute the Apple Software solely for non-commercial purposes "
