Siri may phone home with Ask Siri disabled

from blog The Desolation of Blog, | ↗ original
Whenever I install a new version of macOS, I always disable Siri in the setup screen. In fact I always disable Siri on my iOS devices too. I have no interest in Siri, and I don't want my devices to phone home to Apple with so-called "anonymous" data that always turns out to be less anonymous than claimed. I expected that the OS would respect my setup screen choice, and indeed if I look at the Siri pane in System Preferences, everything looks disabled.
