As a TV centric distro, there is libreelec https://libreelec.tv/ You can use it to stream media from jellyfin, plex or other streaming platforms with plugins
It runs kodi that you can also use in other distros as a package
Kodi supports hdmi-cec, which allows to use your TV remote to control kodi, the hardware needs to be compatible too though (raspberry pis are compatible) There is also a mobile app, Kore, to control kodi on local network
The UX may not be as slick as androidtv/appletv but it is customizable
Microsoft has set up copilot to make contributions for the dotnet runtime https://github.com/dotnet/runtime/pull/115762 I'm sure maintainers spends more time to review and interact with copilot than it would have to write it themselves
