This is maybe a little paranoid but… i have a jellyfin server that i let some family members use. one of them intends to use an app for apple tv, which i think is swiftfin or something like that. i am a bit skeptical about smart-TVs and the data they phone home with, so i was wondering if there is any chance that i could be compromised due to the linux isos i host on jellyfin due to some sneaky smart-TV stuff?
You’re not just being paranoid.
By my read, Roku just changed their terms of service (this year) to allow them to report back to their partners what I watch from other services and my home Network server.
So I don’t use Roku devices anymore, myself.
Kodi is the (most obvious) Raspberry Pi project that can do a decent job replacing Smart TV appliances.
That said, your smart TV, itself, is probably too lazy to include a 5G antenna to phone home. So you can probably just never give it Wifi credentials, and be fine.
If you’ve given it Wifi credentials, and didn’t read the terms of service, I can save you some time - if you didn’t buy it in the EU, it’s spying on you in nearly every imaginable way.
So i am not concerned about the way i consume the content, but i am sharing it with family and am concerned that the way they consume it can comromise me.
I.e. smart TV or apple TV phones home with “this person watched a file called The.Matrix.H264.PirateGroup.mkv from jellyfin.myserver.com”
