They are probably also using MoltenVK, something that Valve bought and made open-source. Otherwise it is probably just their old Rosetta x86 to ARM transition layer. WINE had x86 MacOS support for a long time already.
That is exactly what I mean: Leech off open-source projects, contribute back the bare minimum (and not even upstreamed) and then make a big announcement about the new “Apple Game Porting Toolkit”™.
WINE is the foundation, but they added own stuff for their hardware.
Yes, they re-use tons of stuff from WINE. Yes, they should actively contribute back. But no, it’s not just “normal WINE”.

Why “bet”? It’s all open source. Just take a look: https://github.com/apple/homebrew-apple
A 3.5 MB patch is more than “just normal WINE” though.
