You can hide any channel apps that clutter your screen. Select the icon, hold down the select button on the remote, and when it starts to jiggle, press Play/Pause button. You can also move the icons around.
If something is legal, make it illegal and then make Apple retroactively guilty and pay back taxes from when it was legal. Does that many sense? (I'm sure the pedants out there will point out why this is the wrong interpretation)
The AppleTV isn't just a YouTube player. It does other things and continues to do them well. In fact, the third gen model continues to gain content and functionality as time goes on. So quit with the trolling remarks.
