An overloaded court system means that defendants are put at a disadvantage and can likely be strong-armed into an agreement that is unfavorable. At least with agencies, companies knew where they stood, after all, most companies probably have a few former agents on staff.
Now it's, better hope you don't lose an injunction and you get a judge capable of understanding the technical reasons why your company should be allowed to operate in that capacity.
I don't think this is the pro-business win that conservatives claim it is. It just changes the rule of the game in ways that I think favor the government. If an agency gets an injunction, then continues to press for continuance based on the fact that they don't have the resources right now, and a judge buys it, then the company end up in judicial purgatory.
