That Chromecast watches every damned thing you do down to the last click. I'm using the same thing and have maybe 50 or so rule blocks for it on the PI hole. I was thinking of making a generic Android tv box from scratch. Hell you wouldn't need more than a used nuk or mini pc and a drive. Everything else you can setup how you like including adding plugins to help de- Google and get some privacy back with YouTube . Course the cost of that has gone up a lot since I planned. Try the Nvidia Shield Pro if you want a lot more power and less stuttering. It's at least not made by Google.
