Seems like this violates a few of the notice requirements most clearly:

(ii) Carriers must allow customers to reply directly to emails containing CPNI notices in order to opt-out;

As it came from a no reply address.

They have "If you prefer to opt out of letting Fi use and share your CPNI with Alphabet and Google services, you can do so by replying here" text in the email with "here" being a hyperlink that takes me to my main google fi profile page but doesn't even turn off the opt-in.

Looking forward to absolutely nothing happening! Is there even a private right of action?
