Altho there's definitely been problems w/ menus on both dads and blu-rays over the years, super annoying the backend libs keep changing and breaking stuff in Kodi.
The problem is the toolkit offered, more than anything else. Kodi needs lots of native code hooks into the OS, which Tizen, WebOSTV, etc don't support, or at least don't give access freely. Otherwise Kodi could be on every platform..
Most TV OS's that aren't Android TV or Roku require you to write web-based apps (unless you're Netflix or YouTube, but another story there) which abstract all the 'good stuff' out, so impossible to run Kodi on.
Roku is an even worse mess (forcing you to use Brightscript, a digital signage language they bought forever go and still maintain)
I was suggesting that instead of the pre-installed OS on Vizio TVs (which is Linux and systemd based according to the lawsuit), you could install your own OS and then run Kodi on top of that. Since Kodi already supports running on Linux, it should not be hard to do this setup once the lawsuit concludes and the code has been released and the installation procedure documented. So the platform offered by the TV doesn't matter, because you'll replace it with a normal Linux one and run whatever you want on top.
For the problem of running Kodi on the web and web-ish platforms, maybe WASM is the future? There is also emscripten for converting languages normally compiled to binaries to JavaScript.
For Brightscript, maybe a similar approach to emscripten would work, transpiling from other languages to Brightscript, possibly via JavaScript. Or I guess a second app based on Brightscript.
