Apple insists that the affected sites are mostly cinemas, theatres, concert grounds and similar locations, but it does admit that it could be used in “covert police or government operations which may require complete ‘blackout’ conditions”.
According to RT it could also be used to prevent whistleblowers like Edward Snowden from taking pictures and broadcasting them on the interent.
Apple said that the wireless transmission of sensitive information to a remote source is one example of a threat to security.
But it said that this sensitive information could be anything from classified government information to questions or answers to an examination administered in an academic setting.
