The League, which is officially 32 independent businesses, does not have the right to do what they did. Comparing them to Apple is a poor analogy because Apple is one single business.
You can argue no one was forced to buy it (and you'd be correct) but that doesn't matter. The courts didn't "invent" anything here. The law forbids independent businesses from doing what these 32 businesses did.
That would only make sense if the teams were suing the league for rights to their own broadcasting. How is this different than NBC having sole rights to broadcast the Super Bowl?
The NFL picks and chooses which games will go to what market already, and it had this other option to have access to all games through a single option.
What will come of this will be pay-per-view for every game. It'll cost $50 for a Cowboys game because they know people will just team up and watch together at somebody's house. Or, we'll be buying seasons for given teams, or collections of game packages, etc.
This is going to make things more expensive and exclusive, not less.
