I'm really not concerned about future Sony or Nintendo coverage but seeing how DF is ok with being an advertising platform for a console manufacturer or just hardware in general definitely leaves a bad taste in people's mouths.
DF presents themselves as a pure fact driven tech outlet. That doesn't interfere with showing or analyzing any graphics card or console sent by the manufacturer - but the fact that they're acting as a promotion platform makes it look like this:
Gaming journalism and the often uncomfortably relationship to video game companies basically - that's a very delicate topic and why we see a bunch of genuinely concerned folks (calm down fanboys DF went from "360 bias" to "PS4 bias" - you go figure).
