There were definitely specific things that they asked us not to talk about. One example: Angela Ahrendts (SVP Retail) talked to us about the new Chicago Apple Store [0] and asked us not to discuss it until its public announcement.

I don't think the town hall events were confidential. My understanding was that they asked us not to take notes or use electronic devices to be polite to the speakers. They explicitly told us when certain information was meant to be kept secret.
