It's always funny trying to have these conversations. I don't care what type of game you play, I can only do my best to explain my preferences, why I like what I like, what people I actually game with say they enjoy.
Meanwhile, pointing out that for some people other styles of game are better than the base assumptions of D&D and the traditional role of the DM I get "NOBODY SAYS THAT!!!!" Yet we've just had a couple of pages on how the GM needs constraints and that it makes it a better game. It's not that the DM is power hungry and abusive. It's just that the DM having official constraints on them prevents them from being power hungry and abusive. Not the same thing at all!
Either you trust the DM to run your game or you don't. I choose to trust the DM until proven otherwise. Even if I'm proven otherwise I'll chat with the DM and see if I can get them to see what the issue is (I've done this a couple of times with new DMs). If I can't resolve the issue then I doubt any amount of rules or constraints will fix the issue, they'll just look at it as a challenge to see how they can work around them. Because D&D is built around the idea and the DMG repeatedly states that the DM is just one player of the game with a different role. The game is about everyone at the table having fun. It's worked just fine for me for half a century.
If something else works better for you great. Just don't say that constraints are somehow inherently better or dismiss the opinions people who don't like knowing that the DM is constrained by the rules.
