It will be very surprising if we see any benefits from cutting Rosetta 2, especially worth gutting all the games and software this has empowered via Steam/WINE/CrossOver.
If Valve shut down Proton to force developers to release Linux versions of their games for the Steam Deck it would be unequivocally bad, right?
And that's also entirely orthogonal to hardware - the hardware battle between ARM Mac and ARM PC is really a battle between Apple and Qualcomm (Apple won).
In hindsight, rather than relying on Snapdragon, Microsoft should have started designing their own high-efficiency ARM SoCs 15 years ago like Apple did. But I mean, everything is clear in hindsight isn't it.
Windows still owns the corporate drone desktop, but, oddly enough, that’s now being served as a VDI through a Linux thin client.
Forcing people to create a MS account to log in their Windows computer, that's because of backward compatibility?
Pushing Copilot absolutely everywhere, that's because of backward compatibility?
GitHub being down almost daily, that's because of backward compatibility?
Them not having to support 30+ year old software means that they can be more nimble and make better hardware choices.
Look at the mess that Microsoft has made for itself by setting the requirement that software made in the 90s must still run on modern OSs and hardware. It's bonkers and is slowly killing the company.
