Check out TrackerControl on the F-Droid app store. It lets you block Internet access to individual apps and selectively block trackers and other analytics. It does this by acting as a VPN in the android OS so it won’t work while on another VPN but that’s good enough for my needs.
I use a Chromecast with Google TV everyday and I do not receive autoplay ads on the home screen. You are free to disable ads on the home screen in the settings and you are free to install third party home screens.
In fact, the only interaction with the home screen that is required is when I see it briefly before pressing the Netflix button on the remote which I have remapped to Plex or jellyfin using the button mapper app.
Even with the default home screen you do not see auto play ads unless you select them and continue watching.
Thanks for the recommendation, I had not heard of that but it looks like a common solution so I may try that later! Here is a helpful looking guide I found in case anyone else is curious too. https://www.ethanmad.com/post/jellyfin_remote_access/
If I can’t masturbate to every character in every game, then what’s the point of gaming?
