It didn't start with the dev making fun of someone's death. It goes way back. It all starts with the main character actress herself and her far left leaning, woke and narcissistic remarks, she likely had no impact on the game and its story whatsoever, doing nothing more than motion capture and voice recording sessions, but people look for any excuse to take a piss at a anything.
The second one, were those "groundbreaking" discoveries people made of Veilguard devs joining Sucker Punch, with some of them having lead dev positions at the studio. Those likely didn't have an impact on the game either, as big number of them wouldn't join the dev team until early 2025, a point in time, where the studio most possibly had wrapped up with the story, mocap and dialogue sessions. At that point, devs were and most probably still are, doing optimisation and bug fixing, which is something that devs do during, you guessed it, the last 6 months to a year preceding the launch of the game.
Veilguard devs likely couldn't change anything at that point, as the scripts were already at a pretty advanced stage for any changes to be applied. But alas, like I said, people hold onto any excuse they could find to bash anything.
