Ok, because the quote I saw was "Bell and Rogers have more than enough funds to make as high quality a stream as Amazon does lol", but a bit further back talks more about the overall broadcast, so I think we have two parallel points being discussed.
I was seeing a lot of complaints about the TSN and Bell streaming platforms during the game, I figured that spurred some of this.
Not sure what revenue models, distribution, or media rights share has to do with whether or not Amazon can put out a good broadcast though.
Wrt the NHL, a lot of stuff is actually contracted by the broadcasters, not internal talent, so for example, it's the same cameramen regardless. A lot of expertise is basically the same regardless of whether it's TSN or SN televising the game. I imagine that is the same with Prime, they've contracted the same companies for camera work and I suspect the same directors ect as all the other broadcasters do, the difference boils down to the platform they broadcast over, and the panels and on air talent they set up.
