I think what he was getting at is the main purpose of Metrotube is that you can login and do all those things through its UI and not the lame ass one that is the default YouTube app.
By no longer using that functionality he sees no desire or need to use the App. But the app is like $1.99 or something, what's the big deal right?
Lol I guess, but imagine all the other apps that I could've bought with $1.99!
