I use bit_chute and odysee regularly. May not be available as an official Channel yet but there certainly is no ban on it. (unless you can point me somewhere to the info). You can always just cast it to your TV using the Roku's DLNA. I still remember when Rumble was developing its channel, it rarely worked, but that wasn't Roku's fault. It is better now with the Rumble's content creator subscription feature added to its Channel, but still sometimes better just to cast from the Web since the Search function is still a little lacking in the Channel version.
From what I understand , bit_chute is currently working on its Live Streaming Capability for its creators, so maybe creating a Roku Channel isn't a priority. Roku doesn't create the Channel, it just provides the platform. It is bit_chute's perogative/initiative to develop and produce a Channel for the Roku, not the other way around.
Hope that helps. Maybe just misplaced anger or simple misunderstanding.
Web Video Caster is the preferred method since it is available in the Roku Channel Store. It is free to install and use. You can upgrade to remove the ads from within the App and enable some premium features. I think $3 or $4 (one time purchase), otherwise, still completely usuable as free.
From the Roku Device... STREAMING CHANNELS....SEARCH.... Web Video Caster - Receiver
1. Install the Web Caster Receiver from one of the above methods to your Roku Device.
2. Install the Web Video Caster App to your Android or Apple Device (mobile phone/tablet, etc) from the corresponding Play Store or App Store)
3. Make sure your Roku device and Web Video Caster are on same network.
You launch the App from your mobile device and run it from there. The receiver just sits there on your roku device, you don't launch it....it just interacts with the App on your mobile device.
In a nutshell, you use the Browser function of the App to navigate to the web site and the media you wish to play. Then you select the media (video, web stream, podcast etc.), it will establish a connection with your Roku device (via the installed receiver channel) and your videos will play on your TV. You can then use your remote to fast forward, rewind, pause, etc.
You can also use the Web Caster to control any Media Servers you have setup, etc. Plenty of uses.
Includes tutorial and Help...Easy to use once you get hang of it. A little learning curve, maybe.
Hope that helps.
Now, if you have Apple device, look into Roku's AirPlay that was included in 9.4 Roku OS update. Similar principle, but I am unfamiliar with it. May work easier and better for some people. I did attempt an AirPlay for Android App but my Android devices or Android software on these devices may not be compatible as it didn't work.
