All of this in slavish servitude to the living corpse of a God-Emperor
They are literally using the chaos propaganda line about a corpse emperor, which is objectively wrong within their own universe as the Emperor is actively holding back a chaos invasion through the webway and is the beacon that allows humanity to travel safely through the warp. So yes, Games Workshop has taken the side of chaos.
As the left loves to say, history is written by the victors. "The right side of history" implies that they are willing to commit any atrocity necessary to win. Exterminatus is mild in comparison to the horrors chaos(and progressives) are willing to unleash, and thus wiping out a planet is in fact the Emperor's mercy.

So much for being on the right side of history.
