When Apple started soldering their RAMs and SSDs, I predicted that Macs and macOS would be slowly locked down like other iDevices. I was mocked here and elsewhere for pointing this out. With Apple Silicon, Mac hardware is now like iPhones and iPads (with only the bootloader remaining to be locked). With it, they have ensured that all non-Apple OSes can only run crippled on Macs. So now they've also started taking away our control through the ios-ification of macOS.
Intel and AMD CPUs seem to do fine, and still are better than Apple Silicon in performance, without needing to resort to any "unified memory" architecture. And the newer replaceable / upgradeable CAMM2 (Compression Attached Memory Module) RAM is a good compromise to it with even more RAM bandwidth, and lower power requirements. (Sure, they may not be as fast as on-package DRAM or HBMs, but as everyone is now finding out, sacrificing our computing freedom to the whims and mercies of corporates is not in our best interest).
