“A significant amount of users have been receiving 15-day suspensions as a warning shot from Xbox,” they add, including photos from users as proof. “We STRONGLY recommend removing any and all emulator apps from your console in retail mode immediately (dev mode is unaffected).

Who else would cause Microsoft to be enforcing actions against emulation? Nintendo is literally the only one delusional enough to think their incorrect interpretation of the law is correct.
