The owner is a Google employee, but for the sake of safety it should be owned by a real Google org. I've just asked them to migrate it to their OSS org.
Unfortunately the app creation flow on GitHub makes it impossible (for now) for a normal org user to create an app for the org, so apps end up getting created on personal accounts and become load bearing. We've got a work item to make it possible to give app creation rights to your org members, I've got it high on the priority list for the next six months.
Re:payment As I understand it each org that uses the gemini cli agent puts their api key in their actions secrets, which gets picked up and used to call Google inference APIs. So the org these comments are in is paying for the inference.
