"Cisco IOS (Internetwork Operating System) is a proprietary operating system that runs on Cisco Systems routers and switches."
Of course, Apple licenses (only) the name, and tweaks it into iOS.

Well.... so is ARM... they started with the M0, then M1, etc... "M" is their family of MMC less cores.
You also got the "R" and the "A" cores. And they all follow a numeric naming versioning schema.
Sorry, but IMHO, Apple sucks at this. I still wonder how much money they must have paid Cisco for the IOS name. And, surely, ARM didn't take it standing.
I mean, what's really interesting, is the the Apple SoC ASIC use ARM cores... and I'm darn sure they have a bunch of M cores for the HW interface, a few R cores for the real time IO and a bunch of A cores to support the Applications, plus the DMA, the matrix, L2 and L3 managers, the MMC, bus controllers, the multimedia and the modems....

Whatever it is, I really enjoy using the M2. The 12+ battery life with constant use is fantastic. I often go a few days on a charge if I'm not doing much computer work. It also drives my external (32", 4K, USB-C connected) monitor vastly better than the 2020 Intel MBP did.

The chronology doesn't correspond to the numerical order though, rather M3 came first, then M1, then M0 and then M4. For some reason they skipped M5 and M6 and jumped to M7 after that.
That's internal data from my company, i can't disclose that. But the one i worked before had almost the same stats and so on. Mac used to be very sturdy, but since a decade or even more it's not like that anymore.
Power management is a HUGE part of designing portable SoC's.
I have some experience at that... from work at Broadcom, before they bowed out ot the market. Indeed, Apple used to buy our cell phone SoC's.
