That's a price fixing/cartel case not a first amendment one.

Isn't that the point? What you prosecute is not related the first amendment, despite the actions being protected by it.

This case is clearly price fixing, not first amendment.

The radio stations weren't broadcasting their prices to consumers, but secretly communicating with competitors to form a cartel, which is forbidden. Doesn't matter if they were radio stations or grocery stores.
