Samsung should have just taken the hit and abandoned Android years ago and completely switched to Tizen when their brand was strongest. This slow bleed out they're currently going through isn't going to end well for their mobile business and given their dwindling fan base I doubt there will be much interest in products running a new OS.
I wasn't on GAF at the time, but I remember reading around the web when Amazon started their whole Fire OS platform and the general Android community thought it was a terrible idea because they got rid of all the Google stuff, new store/etc. However looking back at it makes me think Amazon was one of the smartest companies that utilized Android because now they have a pretty large business selling all of the digital content that pulls in the real money like apps/games, music, videos, books/comics, and they didn't pay an arm and a leg for R&D since they just branched it off of Android.
