Did 9 Million Cable Subscribers Cut The Cord?

WSJ: 
Did 9 Million Cable Subscribers REALLY Cut The Cord?
Survey reports 9 million have cut the cable.
Cable companies: "We don't see it."
Someone's either blind or lying, who is it?
(Hint: you can always trust Comcast. They've never lied to anyone. EVER.)

Note that all they talk about in this piece is internet TV, nobody mentions Free "Wireless" TV with an antenna.
