I just read Google will not make YouTube available on the Amazon FireTV beginning next month. This may be negotiating or posturing, but it may impact cord cutters. Story here https://arstechnica.com/gadgets/201...youtube-support-from-amazon-fire-tvs-in-2018/
For me it was a huge deal when I couldn't get Amazon Prime Video on the Chromecast. By contrast, removing the YouTube app from Fire TV is a small disappointment. Content-wise, it's not really comparable, at least IMHO. Plus, there are dozens of other ways to get YouTube on the bigscreen if desired, including at least two ways without ever leaving the Fire TV input... the new Silk browser or Kodi. Both are more cumbersome to use than the app however.
In any case, I do wish Amazon and Google would learn how to play nice and cut a deal. It doesn't do anybody any good when you cut off access to your content to a large group of device owners.
PlutoTV is interesting. It seems to have all the castoffs and misfits from HDTV. I do like the Slow TV (trains going through Norway). They have some fun/quirky stations. Some decent older movies...
A couple months ago, I installed Pluto on Fire TV and explored it for about 15-20 minutes. It was mildly interesting, but really nothing there for me. I've never looked at it again. I know it's getting lots of attention and some investment, so I'll check back at some point.
Currently, we subscribe to PS Vue, Amazon Prime, Netflix, Curiosity Stream, and PBS Passport. We get Hulu via DD's login. We never leave the Fire TV platform/input. There's way more content there than I have time to sit in front of the tube. New content comes faster than I can add it to my watch list.
