Moore's hit was incredibly similar to one thrown by former Oiler Josh Archibald a few years ago in the Covid season. For the same hit, Archibald was suspended a reasonable one game. Player Safety should have at least pursued a one game suspension, but to let Moore go without even a fine is an egregious miss by George Parros and the NHL.
In the playoffs the referees and player safety is known to move more lenient with physical plays - but this wasn't a hockey play. It was a direct attack on Desharnais with intent to injure, and should have been addressed by the league as such. Now, we'll have to see if the Oilers take justice into their own hands tomorrow night.
