Maybe you haven’t been convinced by a good enough argument. Maybe you just don’t want to admit you are wrong. Or maybe the chaos is the objective, but what are you knowingly on the wrong side of?
In my case: I don’t think any games are obliged to offer an easy mode. If developers want to tailor a specific experience, they don’t have to dilute it with easier or harder modes that aren’t actually interesting and/or anything more than poorly done numbers adjustments. BUT I also know that for the people that need and want them, it helps a LOT. But I can’t really accept making the game worse so that some people get to play it. They wouldn’t actually be playing the same game after all…
That’s why you design for accessibility, and don’t try to cram it in at the last moment. It’s not actually difficult, it just requires engineering discipline.
There are also plenty of Dark Souls clones for people like you who demand nothing but punishment.
I don’t need a game to be hard, I need it to be consistent and well thought-out. Animal Well for example is a rather easy game, but because it only has one difficulty, the developer was able to keep a very tight focus on the world and puzzle design. Everything is layered there, because they don’t have to be containerized and sliced into pieces to account for adjustable difficulty settings.
Or they could have thought it out even better and included difficulty settings.
They have every right to ignore accessibility, but it will always limit their audience.
