Ah, I see. I don't think it's quite the same thing, though, because their previous opt-out problems have been when they actually create a new feature, make it public, and make you opt out to make it less public. This situation is, while not ideal, maintaining the status quo (relative to auto-tagging) but giving you extra controls to make some things less public.

Actually, I had thought you could opt out of auto-tagging (but you had to opt out of it), because I remember doing so. Can't find the control right now, though.
