Could it be the Federal Government, which forced the 1984 consent agreement and the breakup, and the Telecommunications Act of 1996 that pushed the process all the further?
Jerry Pournelle was fond of saying something to the effect of "We have the best telephone system in the world, but we can fix that."
A problem here is that MCI's business directly attacked the heart of the AT&T business model, which had long distance subsidizing local telephone service. They had to viciously defend the former.
The breakup's solution was the Federal Subscriber Line Charge.
I thought they continued on for a long time after that. After all, didn't Bell Labs convert into Lucent just 7 or 8 years ago?
I'm not even sure you can blame that on the company, considering that it's the shareholders who fundamentally encourage that behavior.
And it destroyed the scale: after the 1984 consent degree, AT&T was a much smaller company and the RBOCs set up their own quasi-parallel Bellcore, but that did little or no basic research as I recall.
Factor in that one of the prior anti-trust agreements required AT&T to license at a reasonable rate all the output of Bell Labs (e.g. the transistor). And that they used its output among other things to justify their business model.
Look, the 1984 consent agreement may or may not have been a good thing, but we can't pretend it didn't come without some serious costs, and everyone at the time who I respected said that Bell Labs would be one of those. I was an early 20s callow youth at the time, but I agreed as well.
