I very much agree with your comment on an individual level (that of the individual judging the merit of information and opinion they are being presented with). I certainly take provenance into account.

However, I was talking about HN the site. I don't think news websites should (generally) discriminate against sources but the individual readers can (collectively, as with the case of HN and voting) make a judgement call and take provenance into account, including the example you give where an unlikely source makes concessions or gives validity to an argument that they would be usually opposed to.

But the main reason I raised provenance is that the internet has given small individual voices the chance to bring informed insight to the public that previously would have been without a platform. So in this particular case I don't necessarily discount some rando on Youtube making criticisms of SpaceX; they might hold at least some validity. (In this case they obviously didn't.)
