I personally don't believe results should be removed or altered based on human judgement. What if I decide to start a competing service that Gabriel takes a dislike to? Or decide to start a hate site for DDG[1]? Do they not deserve a place on the internet? Is it up to one person to decide this? For neutrality to work it needs to be neutral for absolutely everyone, or atleast that's how I see it.
[1] These are purely hypothetical. I'm a big fan of both Gabriel and DDG, and I'm not suggesting he would ever do these.
