This is bad, but not as bad as the "Unlock Premium" ad every single corporate/enterprise Teams user got (locked in the title bar on Windows and macOS). Hiding the ad required an admin to turn off "self-service", a hard to find setting buried in the "Org Settings" within Microsoft 365 admin center. I can't even blame this on AI/Microslop.
