"I do not know if Management is willing to hold an online Q&A session"

No way. I can't remember them ever having one -- and for good reason, they wouldn't be able to hide from the real questions, and wouldn't be able to re-direct peoples attention in real-time to withhold certain information they do not want getting out. Also they would get their asses handed to them, easier to cower behind email replies for Q&A (that is if people's emails aren't still being ignored).

Announcements are easier and safer for them. They can word it how they need, spin the situation as they like and omit vital information where needed (vital to shareholders, not necessarily withholding market sensitive info - although that's debatable with some of the information they've withheld but probably as a matter of perspective).
