Not saying your wrong but I hadn't that and I work for comcast. Also My peacock still works so unless an employee account still allows access or everyone that had activated their account was grandfathered in you MAY be wrong.
I have comcast/xfinity and they canceled Premium access to Peacock for all subscribers and you had to subscribe to watch anything more than a s1 ep1 of any show. All live events are for subscribers only.
