Well more generally speaking I honestly don't think most people care, they will simply play games on whatever box they have.
Of course, but you can't deny that the general public knowledge of what box is the most powerful will be determined by the general consensus among gamers. And the results from DF plays a big part in this.
I can understand the wish from Rangers, DF is the goto place. But in this case I am not worried, until DF gets caught cheating to promote a certain console they are fine. The technical analysis they provide are rarely open for a subjective interpretation.
And unlike machima, a marketing firm can't pay them to be xb1 fans, it would be revealed instantly.
And bias is out of the question, the whole last generation was spent on showing how far or little the 360 was ahead on multiplatform games
