Yes, it's an attitude that I never saw before 3e, but 3e's avowed goal was to be player-centric, and that with the overall change of mentality in the world (and about that one, I'm not saying that it's a bad thing, my daughters are millenials and I really enjoy our discussion and greatly value their perspective), has created a generation of players that is quite different. I come from a generation where respect was due in particular for work and in even more particular for the DM's work in preparing the game and running it for the players.
This is, by the way, echoed in Tasha's section about session Zero: "The players will respect you and the effort it takes to create a fun game for everyone. The players will allow you to direct the campaign, arbitrate the rules, and settle arguments. When you are talking, the players are listening."
It is, obviously balanced by the DM's responsibilities: "You will respect the players by running a game that is fun, fair, and tailored for them. You will allow every player to contribute to the ongoing story and give every character moments to shine. When a player is talking, you are listening."
And finally with the respect between players: "The players will respect one another, listen to one another, support one another, and do their utmost to preserve the cohesion of the adventuring party."
These might seem a bit old fashioned to some, but I think that "a priori" respect and trust are really critical to enjoy the game...
