That video has earned me a grand total of $500. And most of that earning happened a couple years ago. I have never run AWX for any of my own projects (or deployed it for any clients), so I have not materially benefitted from it in that way either.
I can guarantee you that video and my short chapter on AWX in my book have earned Red Hat many, many multiples of that through companies adopting an AAP subscription.
I also literally built the AWX Operator that Red Hat is still maintaining to this day: https://github.com/ansible/awx-operator/graphs/contributors
