Apple was slow to act on FaceTime bug report, which came from mother of 14 year old who found it

That’s not a bug It’s a feature. Can you imagine how much Apple made selling this feature to Law Enforcement and Espionage agencies? Just think of the money and time they save not needing to install a surveillance device or get a court order to listen in on you. Now that Apple has lost that revenue stream I can guarantee you the next generation iPhone will be more expensive.
