Have you actually used MacOS without perusing Apple's services? It's horrible, because MacOS is designed with the assumption the user has an Apple account.
It's not obnoxious like Windows 11's badgering for a Microsoft account, but it manifests in parts of MacOS (namely anything to do with the App Store) flat out refusing to work until an Apple account is provided.
I may have to make a throwaway Apple account just so I can do something as mundanely basic as updating the system applications.
