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)
