Re: He is correct
But consider this. The current AT&T and Verizon both came about through the RE-merging of the various Baby Bells that were created from the breakup of the original AT&T. The point is, mergers and acquisitions are a natural course of business since with size comes scale and integration that smaller companies can't do. And there's no way to predict how much is too much, so the end result is that any serious breakup just starts coming back together again, around any laws that get in their way.
