In fact, reading into it more - they simply say "apple used our source code" this sounds almost explicitly like they are not paying, at all.
On top of that, Apple's DX to Metal code is not re-distributable. So yes, this sounds like more of the same from Apple.
CodeWeavers released an annoucement when Gaming Portal Toolkit was announced.
