I understand where you are coming from, but I personally think that it's reasonable for a TV to show me sponsored content that is TV shows. I don't see this any different to how Netflix or Spotify show sponsored TV shows or music.

But my friend has a Samsung TV and it shows him ads for things he can buy from eBay, ads for games etc. in a similar area .. and yeah that's nonsense, that would really get on my nerves.

I think you can switch it off. Poke around on menus

I don’t even have a Home Screen on my C9
