To the contrary AT&T proved itself incapable of delivering end-to-end innovation. Sure it lowered the cost of intercity links for long-distance calls dramatically but couldn’t pass savings on to the consumer. Picturephone was a technical tour de force but demonstrated AT&T couldn’t deliver new services other than little things like call waiting and caller id.

Notably high profits from long-distance dialup calls kept online services stuck at 2400 bps for most of the 1980s. Futurists circa 1960-1970 thought online services were going to become widespread about 15 years than they really did and AT&T was the #1 thing to blame.

Bell Labs?
