His thoughts on 4e and the DM pipeline, on the other hand, don't baffle me.
So, try and picture this difference.
In one game, you have a system that removes more work from the DM, such that the DM is more of a neutral combat referee. As such, it is easier to transition from player to DM and vice versa. Because the divide between player and DM isn't that large. That has a lot of advantages (most players can DM), but it also has a certain disadvantage- if there is nothing about the edition itself that drives growth, then it will be harder to find more DMs. Every table might have a DM, and the players might be able to rotate among themselves, but you're not creating new DMs.
There is certainly a comfortable middle ground between 4e DMs (player plus+) and Gygax-style EXTREME DMing (every DM is responsible for 20-30 players, on many nights, with hours of prep time and so on). But I can certainly understand his point.
I guess I don't see how 4e put DMs in the position you describe?
The DM still very much has to do more than "referee". They run the world. They decide what exists where, who is doing what, how the world responds to the player characters, and create or facilitate (depending on game style) the unfolding story. Just like in 5e, just like in 1e.
The 4e DM just doesn't have to correct mechanics on a regular basis, has better tools for creating encounters that do exactly what they want, and doesn't have to memorize character sheets (bc the game is balanced), or spend hours and hours doing mechanics-side prep, in order to know what will be a challenge vs a cake walk.
4e has downsides, but IMO, none of hem have anything to do with DMing.
