I'd also remind you of the cost of a telephone system with monopoly status that didn't even let you install your own phones in the house for a long time. And which led too skits like Lily Tomlin's "We don't care. We don't have to. We're the phone company."
Bell Labs was able to exist in large part because AT&T was a quasi-government regulated monopoly. You couldn't really have one without the other. (And I'm not sure I'd even say at&t had shady business practices. But they were a de facto monopoly.)
