Apple has these signs posted all around the conference hall:
Of course, while I see Apple's point, and I'm going to do my best to respect their wishes, I think that this policy is extremely stupid. Apple needs to get the word out about their platform, and how great it is. And any little thing that can be done to help -- posting information on blogs, discussion forums, mailing lists, etc. can only help Apple in their quest to keep the Mac OS X platform relevant.

I totally agree this is a stupid thing to do on Apple's part. But honestly this is what business needs and demands to protect itself. Its a self-defence mechanism.
And the world is not ready to be completely OPEN.
