I guess what they call it now is the Explore page which is all Ellen and Tonight Show clips.
And is that the main page for you? When I open the website or the Android app I get "Home". "Explore" is a separate tab. "Home" is pretty much filled with recommendations from channels I've watched recently, no corporate stuff (excluding ads).
I do see the issue of recommendations being flooded with one topic you've watched recently, but I generally don't have too much of a problem with it. When the recommendations stop being relevant/interesting to me, I tend to shut off YouTube.
Home page is the one that's being promoted to you.
