Ask HN: Is it impossible to disable Siri on macOS 27?

A user reports difficulty fully disabling Siri and Apple Intelligence on macOS 27, finding that Siri processes continue running even after disabling the features through Settings and Screen Time. Commenters suggest using Screen Time settings to switch to "Siri Classic" to disable Apple Intelligence-specific features, or disabling launchd services directly, though some note this may require disabling System Integrity Protection.
