The Feist case was about the expense accrued in aggregating the information and the incentive issues that arise if those efforts are not protected.

The NBA case was about the division of rights between the competition organizer and those attempting to report on it. Specifically, are the reporters required to delay their reporting efforts when the only information being reported generated by the event is factual.

If I understand correctly, this ruling doesn't preclude the event organizers from banning all electronic communication devices from the premises. It just prevents them from pursuing any civil penalties from those that report on the event.
