I think they may just be a mind melted apple fan boy. Its either that or apple managed to make those Cybermen earbuds from Doctor Who, ya know the ones from the episode with the Daleks and the dimensional rift.

Probably was just for the old Intel Macs.

Proton/Wine could be used on OSX for a long time. Wine for ARM has also been a thing for a while. But it only worked with ARM Windows software.

Combining Wine with x86 emulation has also become a thing in the last few years. And rumor has it that Valve have beem dabbling in it as well for Deckard. But I don't think it's very widespread yet.

But that is probably about to change when Valve are increasing their ARM Mac efforts.

Because they are selling games on this platform today and the reasonable expectation would be that they properly support it. If they deem it too much of a cost then they can exit the market rather than half ass it.

Apple doesn't care about maintaining compatibility. Look at their previous changes such as PowerPC to x86 and forcing 64-bit only applications.

Apple not keeping legacy cruft is why they were able to move to ARM so quickly. For all the grumbling about cutting 32-bit support couple of years ago, this is what allowed them to do that (among other things). And, as demonstrated, developers like Valve take action only when they are forced to. Windows and Linux on ARM are stuck in the mud with no end in sight while Apple is almost done with the transition.
