Comcast XFINITY TV → HBOGO on SAMSUNG SMART TV's

I remember hearing about how Comcast/NBC was doing a partnership with Samsung for some various projects regarding set boxes and content delivery using SAMSUNG'S SMART TV platforms. So anyways it has been a few years since that announcement came out and I was wondering if Comcast, if at all, is even planning to allow SAMSUNG SMART TV to have access to HBOGO. Currently, as far as I know, you can't run HBOGO on SAMSUNG SMART TV's as Comcast is not listed as an available content provider. Is there a particular reason why almost all the other TV providers like AT&T, Verizon, COX, TW, and DISH are allowing it but not Comcast? What is Comcast's angle for not participating in this?
Thanks

Comcast blocks HBOGO from TV-connected devices. They want to protect their video subscriber base and not get people used to watching HBO through the Internet.

In another thread, I recently posted about an article on Comcast preparing to launch an Xfinity TV application for Samsung Smart TVs: »Re: HBO GO not available from Comcast?

Comcast does support the XBOX 360 version on HBO GO and not the Samsung or Roku versions.

This answer makes no sense at all.

HBOGo is only available to the video subscriber base.

Yes, but they don't want you to use it on your TV and watch stuff that isn't linear or through OnDemand. They only want you to see substandard quality stuff on an iPad or similar.

The whole X1 movement disproves that argument. They're trying to get the internet onto your tv.

I own the X1 and the only apps I have are like Facebook, weather, sports, and traffic. None of them are video content apps

Your opinion or documented fact?

I have a Dell laptop with a Nvidia GPU and HDMI output. I have connected this to my HDTV and looked at an HBO Go movie and found it to be of high quality - at least as good as I see using my HD DVR cable box. The stream to the computer was WiFi 802.11n. Not all laptops are this capable, but I found the experience to be excellent.
