So ... wait for this ... it might blow your mind.
If you, as the DM, are stating that this is the type of campaign that you are going to run, then .... you are, in fact, advocating for a specific type of campaign (a setting, if you will).
You are not polling the players. You aren't saying, "Hey guys, I got nothing. I'm bland like vanilla. So tell ya what- we can run Dark Sun, or do an AP set in FR, or Dawn of Worlds. Whatever, man. It doesn't matter to me. I barely have the energy to keep breathing."
If "wanting to run a player collaborative setting" is the same as "DM comes to the game with the setting decided" in your estimation, most of the pushback in this thread would have been avoided. That's what most people here were advocating, not apathy.
That being said, there's also a difference between "I've got nothing" and "I'm willing to run a game where I ask the players what setting they want because it makes them more invested in the game". Subordinating your desires for the sake of the group is also not apathy.
