You can't withdraw your consent, as you already agreed to waive that option. That being said, as others stated, you can turn off email notifications. Bungie's privacy policy protects your data from most uses outside of Bungie, so you've got very little to worry about there, as well. But, you can't withdraw their right to have, keep, or use any data held that you submitted to their service, as per the above contractual agreement you entered into. Do note that you can edit your profile considerably to remove most personal information, including removing all current connected accounts (by creating a new, unconnected account using one of the three services and connecting it to your account so the other(s) can be removed).
