At this point just get a rasbperry pi, or some similar device, and run it as a regular computer. Firefox, ublock origin, don’t worry about ads, and turn it into a machine that is capable of soooooooo much more. Hell, any PC will work. Steam Deck, NUC, that old laptop you have laying around? Been running little NUCs on my TVs for years and so happy I don’t have to put up with that nonsense.
I’m a linux nerd and I jut run stock Fedora. It’s desktop is like a phone UI, so lots of folks are familiar with it.
I then use a wireless keyboard and trackball. T
here are tons of remotes out there,but I don’t have any experience with then. Let me know if you find a good remote though. 😁
