The specific examples in the thread, AFAICT, are about iOS, not macOS, and the person you're responding to specifically mentioned Macs. It's very hard to find examples of "things you cannot do on an Apple Silicon Mac due to Apple-imposed restrictions that you can do on a PC" that aren't pretty esoteric. (Unless you want to argue that the inability to plug in a better third-party GPU is due to Apple-imposed restrictions, which is debatable but defensible.)
