NBC Sports Gold

Given that Comcast owns NBC, I would think that the cost of broadcasting sports channels would be minimal at most, so I have to wonder why, since NBC owns the rights to Premier League football, that Comcast doesn't make subscription to NBC Sports Gold free to subscribers of the X1 network.  The app is in the Apps menu and was added very recently.  We already pay a great deal for cable, especially if you actually want anything good to watch, so it would be a nice perk (maybe for a specific level of subscription to cable) to have free PL viewing.  After all, when NBC first got the rights to the PL coverage, every match was on, usually on an On-Demand channel.  Then it was only available with the X-1 platform.  Then the Gold package was created.  Maybe it is time for cable to give back to the customers who make them wealthy...
