This does run into the same problem that Wikipedia runs into, that it insists on using “credible” or “reputable” sources but does not really bother to define that, and it essentially comes down to that sources are not “credible” for disagreeing with their beliefs.

Personally, I have yet to see any “credible” news source and the adage remains that every news article about anything I have even the most minor inside knowledge of seems completely inaccurate, especially the politically laden ones.

No matter what mechanism Google uses to assign such ranking: be it their own judgement or simply an agnostic a.i. that lets the masses decide, I cannot see anything good coming from it and there will always be a bias not based in factuality, but politics.
