Hikaru does an amazing job of sharing his knowledge and skill without spilling over the top with information about why certain moves are theoretically better than others 30 moves down the line than only a small percentage of people would understand. The skill gap is insane, but he makes it feel approachable.
Its been fun watching the pogchamps series for the most part because himself and Botez (and a few others) can share their knowledge without being affronting or elitist, but instead exploring and explaining why certain good moves are sometimes hard to find or don't feel natural. Simplifying the language and using arrows on the board to show moves, rather than just blasting chess notation at the screen. You can see them holding back when a player makes a certain move, and then openly assess the goods and bads.
They've shown behind the scene training sessions on pogchamps too, showing a little into the world (again at a much lower level) how you would begin to prep and build your chess opening repertoire that is approachable for someone who is learning.
And then at the end of the day, its also just fun to watch someone who has an insane amount of talent be a complete boss in their field. Honestly feels like the top players are scanning a QR code and know what to do without a second thought [1]

To pin onto this for those who enjoy chess but perhaps don't like the stress of online play, I've found the puzzles on lichess [2] to be a great way to learn and be challenged by the game.
