If you scroll through the replies, he does admit to opting into a feature to integrate SMS and phone with Messenger [1].

No doubt there's a permissions/version and facebook-overstepping-ethics conversation to have here (as always), but this isn't as major as the title implies. It does seem like Facebook continuing using permissions after he opted-out.

For what it's worth, the cell metadata in the post is from over a year before I even opted-into the SMS integration.

The SMS integration was disabled after a few weeks of usage, the app was too buggy.

I have never/ever installed Messenger on phone, yet all calls/texts are in FB. Either they are copying it from WhatsApp servers, or stealing using FB app, not sure.
