If you ask someone what processor is in their desktop, nobody says “Oh I’ve got an x86_64”. They’ll tell you which product line it is: “Ryzen”
If anyone deserving credit for this, it’s Intel after introducing the Pentium line.
In this case I believe they would want specify Apple Silicon because there are multiple manufacturers that produce ARM chips.
I thought the common speculation was that they aren't allowed to call it ARM, because they extend the ISA significantly enough that ARM-the-company was concerned it'd fragment the ecosystem.
Why would you call AMD cpus an Intel because they license x86?
