The link below summarizes classic issues with telcos.
This is nothing new. For instance, in the 70s, telcos have spun a massive computing innovation wave through the invention of Unix and the C language without ever being able to monetize it. (It was a useful invention for them though since it launched some of their providers.)

Currently they are stuck between VoIp and mobile data. Instead of letting innovation happen and users/subscribers select what they want (through a market), they are trying to analyze and understand what to do with them. Besides, they put an expensive QoS burden on top of all services which inherently limit “try out” strategies for their providers.
At the same time, those issues are at the heart of telcos successes. Those “rigidities” explain why they have been able to drive down cost and respect their legal obligation (mainly for emergency dials).
The next few years should be interesting for observer but hard for the telco industry.
