My parents are getting a new tv, and are asking for recommendation. I think all I can influence is the brand/model (not realistic to propose rpi and more complex systems). I instinctively avoid google/android and lean towards anything else open source, so probably LG WebOS… But I had bad luck searching for more detailed comparisons. Maybe you have experience or opinions?
I heard that https://libreelec.tv is pretty good
Its good if everything you need can run from Kodi. It uses its own Linux distribution in the background, so you won’t really be able to install anything else unless you build it.
Absolutely this. Depending on how you use it though, make sure you have a VPN and private DNS setup on your router
If Kodi is used to watch movies and TV shows for free then you’d want to protect your internet traffic from unwanted eyes
