I personally agree which is why I also join every interview with my camera on. Objectively though you have to consider that the job market is a MARKET, and if the seller (candidate) considers they can do just fine without the camera (or anything else really) then you have to accept that fact and move on to another candidate if you can or just go forward with them without camera. Nobody owes anything to anyone here.
Recently I did a few rounds of interviews. I found that I was bombing the phone only interviews but doing well with the camera on. I'm all in for basing part of the interview based on looks vs how someone sounds but I do think stereotypes play a part.
