Looks like roku is going to lose a lot of business by taking away all the channels that were there to include basic paramount app.
As noted, Paramount Network is a CABLE network. Roku cannot simply add it or create an app. That is up to Paramount. Also as noted, if you are complaining about Yellowstone, it's the original production company that made the deal with Peacock.
The point is that there WAS a Paramount Network app until recently. I had it myself just a couple weeks ago. So stop saying there hasn't been one.
The Paramount Network app was a TV Everywhere app that required linking with a paid Live TV service (cable, satellite, etc). Paramount shut down and eventually pulled all of them (Nickelodeon, Smithsonian Channel, Paramount Network, and probably more) several months ago.
