There is an "app" for most commerical services available for Kodi. These apps do not break DRM (they use an extracted Widevine binary from ChromeOS).
These app are not official however and are not in the main repositories for Kodi. Just search the Kodi forums for the service you need and you will find the app (for most services that I know about).
Plex has its own telemetry and doesn’t really make devices per-se. it’s an App, including on Roku.
My hous is basically all rokus at this point. But I do keep the isolated on their own net and behind pi-holes.
I’d love an opensource alternative that can do all the things Roku does. Netflix, Hulu (though I don’t have it), prime, or Plex etc.
Sure with something like atomictoolkit you can do it all in Plex, to a degree. But I even use YouTube for things like guitar lessons/song learning etc.
To be fair. I can probably do that with those options. Roku was simple enough that I can work around. I should probably do some better research on alternatives.
