While I find many things inexcusable about Slater's and Reed's commentary on mic, especially their weight shaming, and certainly what they thought were their off mic comments about Duhamel, IMO that they could even claim to know nothing out loud is entirely on the ISU, who chose incompetence for their marquee championship.
Since I've given up on most of the judges to judge accurately and according to code, particularly across the field, and the tech panels to apply the technical rules consistently, I thoroughly enjoyed Slater's and Reed's emphasis on arms, carriage, movement quality, live speed, size of jumps, and ice coverage, because those are the things I care about. I have the tech tracker to let me know what the elements are, and it seems like the commentators are given access to what is being entered and reviewed, which they conveyed, even if the tech tracker isn't as informative as it has been in other competitions. Thanks to FSU, I'm aware of most of the rules, even if they go through my sieve brain at times. It's not like I learn that much from anyone on CBC, Weir and Lipinski, et. al., and when you have a single commentator, even Barton and Kwong have run out of adjectives by the end of four days. (It's amazing that they make it that far.)
