I think Congress would have to pass regulation to see any improvement and a reasonable level of competition. If this breakup just results in regional monopolies instead of national ones with the same exclusionary contracts with venues, it’ll result in a distinction without a difference.

Yes, obviously they broke the settlement that allowed the merger in the first place r.e. exclusionary contracts, but if they break up the company, they’ll be allowing the successor companies to set up exclusionary contracts themselves.
