> The person is a "Support Community Manager" in Indonesia if you click on their link. They're not the CEO of Mozilla who is supposed to be an expert in intercultural communication.

This is completely backwards. The CEO is not expected to manage intercultural communication. You know whose job that is? The community manager.

The community manager for Indonesia wouldn't be expected to manage communication with Japan, but managing local contributors is absolutely a job for the community manager and not the CEO.
