Truthfully though....this is a major blunder on Apple's part. I'm sure they get an inordinate amount of bug reports, both major and minor, every day. But when someone puts this on your radar on multiple fronts and it goes completely unanswered it's a sign that the review process if fundamentally flawed.
If this lady reported it on the 21st the Group FaceTime service should have been offline no later than the 22nd and there should have been a press release detailing the issue and the corrective action. Instead it sat there for a week until it blew up in their face.
No way to spin this other than a massive failure by Apple. Hopefully they learn from it and are better for it going forward.
