It's not just dumb pipes (ED: dark fiber) they also have YouTube which is ~15% of downstream traffic which they would be happy to stream inside there private network even with peering arrangements.
I was referring to the sale of the 700MHz C Block LTE band.
One of the conditions of the spectrum license was that VZW couldn't restrict what devices were allowed on the network and that they couldn't restrict what applications ran over the network.
VZW got hit with a $1.25M fine by the FCC last year for blocking tethering apps on LTE.
