It's not centrist. It's pro status quo. "Things are mostly OK, and in the few cases where they're a little bit bad, we're here to tell you about them."
Well, in terms of whatever the current Overton Window is, that's probably true.
But if you view "left", "right" and "center" as having slightly more absolute definitions than the constantly shifting Overton Window, it's not really the same. "pro status quo" in an authoritarian fascist regime would not correspond to "center" on this absolute scale, even if in the context of that society, it might be roughly in the middle of the OW.
Yes, obviously as soon as you look at more than one place or time. Think about it, the status quo varies. Also the current status quo is neoliberal, which is right-wing for Europe and South Aemrica, so not centrist in absolute terms.
"Centrist" in relation to the current US Overton fits squarely into the right-wing compared to "centrist" in relation current and past societies in the world.
