I agree with all of that. I'd just love to see what would happen. I'm not even sure it would be good. But it would be interesting.
I suspect a first step would be to appeal and argue it to the Ohio Supreme Court and lobbying dollars such as Ohio has never seen and, failing that, major astroturfing efforts to get a referendum on the ballot (I don't know how easy that is in Ohio).
More realistic is what happened to AT&T. Looking at how awful AT&T is today, it's easy to forget how much worse it was prior to 1984 and how much innovation the breakup spurred (and arguably, how things were better prior to about 2005-2008 when SBC bought the brand from the parent company and reconstituted the mega corp we know and mostly loathe today). You couldn't even own your own handset then, let alone have a choice of providers.
