“A plain-vanilla Android tv box with Kodi and addons would work even better.”
I tried that, but it’s not only very complex, the services that are available disappear without warning. I was never able to get live tv to work properly with Kodi.
You’re right. It’s a game of whack-a-mole. They keep outlawing the good ones, and they pop up again under another name.
This is the way you find out the current working ones and load them.

It’s not a big deal it all if you are even slightly a techie.
