I got that email about my galaxy watch, except those settings don't exist on it.
Additionally, when I disabled it for my phone (which they didn't email me about), I discovered there's actually ad settings in these place where google was permitting itself (default opt in) to share your phone numbers for "better advertising"
But those ad settings only appear if you go to the settings on the web, not in the phone, which is where they tell you to go.
Would you like to count the dark patterns here?
