Oh for pity's sake people.
As at least one person has already posted,
this message has been in the code since at least December when some people saw it due to a glitch (that went away after rebooting):
discussions.apple.com
...so it has most likely been there from day #1 of the M1 Macs, and for all we know it could have been there since Rosetta 1 went away in MacOS Lion. Whatever - there's no reason tho think this is some new, imminent plan to dump Rosetta.
Of course, Rosetta 2
will go away in a few years' time just as Rosetta 1 did, but not until it has been clearly announced as "depreciated" for a suitable period (just as happened with Rosetta 1, Carbon, 32-bit support etc...).
...and just as with Apple's rules on vintage/obsolete equipment and servicing, it is entirely plausible that some regions will insist on it being supported for longer than (say) the US. Then there's the equally plausible possibility of tech import/export controls in some regions, that some people have suggested.
Buy, yeah,
of course it is more likely that Apple have gone bat-poo insane and decided to yank a major plank of the Apple Silicon transition just 3 months in... (I mean, plenty of people have pointed out how devastating that would be - you just have to go the extra step and realise that means that it is probably not true).
Or maybe Intel have found a way to get an injunction against Apple (which would also set a nasty precedent for Microsoft and Windows on ARM) without a single breath of it leaking out into the press (oh, but which Apple was able to anticipate in December) - sure, no laws of Physics would be broken, but really not very likely.
Extraordinary claims need extraordinary evidence.
Now I'm off to the far side of the sun to get my teapot back.
