Frustratingly, recently the latest Plex app stopped working with the block rules I had in place, so I've had to allow through a lot more of the TV's traffic to samsung domains than I'd like.
My primary annoyance is Samsung's monitoring of what I do on my TV, and secondarily their IPTV service, which it seems to default to on startup (I only use apps and PC/game console sources, the TV isn't plugged into or tuned for any channels).
Realistically I need to switch to a Shield TV and hope that nVidia's privacy policies are better... and never buy a samsung tv ever again.
For my Roku I have setup a redirection for all DNS port queries to my pihole as some app developers are getting wise to this and using their own DNS.
It won't be long until they encrypt this traffic and lock us out completely though.
I mean, normal TV it's 90% ads 10% content, do we need to watch even more ads?
Anyone has any idea on how adding a filter like AdBlocker to your router? Never thought about this but it's getting useful af.
