I've been saying this for many years. The reason why US broadband sucks is because the original breakup of Ma Bell has mostly failed. The fault line of Ma Bell's breakup was set to be the local service vs long distance. What should've happened instead was that the Bell system should've been broken up at the physical plant level. ILECs should've been left owning nothing more than the physical plant, selling access to it, at tariffed rates, to any CLEC that wants to provide voice or data service over the last mile.
I'm at pessimist at heart. At best, we can hope that this mega merger is going to get canned. But of course, one can dream about FCC saying to Comcast and Time Warner: "You want to merge, ok, but you end up owning only the physical plant, and anyone who wants to provide video, voice, or data service, can pay you for maintaining the coax, and other than that, butt out."
