I don’t have problems with control changes, subtitles, HUD stuff, all the things that are typically considered accessibility. I reject the idea that any arbitrary piece of a multiplayer game can be unilaterally changed in the name of accessibility. Which is maybe not a take any reasonable person has., but it’s one I’ve encountered.
But your last paragraph is probably right in that for them it was an emotionally charged “every day I deal with this bullshit” and I was coming off as “yeah but like what if i’m mildly inconvenienced one day?”.
