@Harescramblerac are you referring to ads that appear within a screensaver that kicks in while your YouTube playback is paused? Yes, Roku might control that. If you don't want to see ads, then change your screensaver. I've never seen an ad ever if the SS kicks in with YouTube opens. I use the 4K aquatic screensaver, which has no ads.
You're paying for no ads while YouTube videos are playing. If that happens, then your argument is with Google. If it's something appearing with your selected screensaver, then either disable your SS or use a different one. I have never seen an ad within any channel I have open that isn't controlled by the channel provider. Roku does not insert ads while a channel is in use.
