Does Apple sell data on what I’m watching to third parties?
Linux is not a viable option for TV for the vast majority of users. There are no sit back, remote driven apps for the services they use.
JellyFin or Plex. Personally i just use a Linux Mint desktop connected to the TV instead. Web browser for streaming and VLC for downloaded videos.
But JellyFin and Plex exist for people who don’t want that.
KDE Plasma Bigscreen?
